Abstract

[0002] Electronic atomizing devices heat a liquid to atomize it, producing an aerosol with a specific aroma for users to inhale. Atomization efficiency directly determines the device's taste, aerosol volume, consistency, and safety, and is a key factor affecting user experience and product quality. Atomization efficiency generally refers to the atomizing device's ability to effectively convert the liquid into an aerosol. Current methods for evaluating atomization efficiency suffer from low precision, poor repeatability, and the inability to qualitatively and quantitatively assess it. Therefore, there is an urgent need in this field for a method that can accurately, objectively, and quantitatively evaluate atomization efficiency. Summary of the Invention
[0003] This application provides a method for determining atomization efficiency. Using gas chromatography, the absolute release amount of each target component in the atomized product can be directly measured. Compared with the traditional weight reduction method, the atomization efficiency of each target component can be determined separately, thus providing accurate data support for the research and improvement of atomization devices. Furthermore, because quantitative analysis using gas chromatography is used instead of traditional physical weighing, systematic errors of traditional methods are eliminated, improving measurement accuracy.
[0004] Some embodiments of this application provide a method for determining the atomization efficiency of an atomizing device, characterized in that the method includes the following steps: obtaining a standard atomizing liquid, the standard atomizing liquid containing at least one target component having a known initial concentration; atomizing the standard atomizing liquid using the atomizing device, and collecting the atomized products generated by the atomizing device from the atomizing of the standard atomizing liquid using a collecting device; obtaining the mass of the target component in the atomized products using gas chromatography; obtaining the consumption amount of the standard atomizing liquid, calculating the consumed mass of the target component based on the consumption amount of the standard atomizing liquid and the initial concentration of the target component in the standard atomizing liquid; and calculating the atomization efficiency of the target component based on the consumed mass of the target component and the mass of the target component in the atomized products.
[0005] The above method uses gas chromatography to plot standard curves for standard working solutions of known concentrations.

Figure 1 The collection device of this application is explained as follows: the atomizing device 1 is mounted on the clamp 2, the clamp 2 is connected in series with the collection device 3 for collecting the atomized products, and the collection device 3 is connected to the suction machine 4.
[0032] An embodiment of this application provides a method for measuring the atomization efficiency of an atomizing device, the method comprising the following steps: Obtain a standard nebulizer containing at least one target component with a known initial concentration; A standard atomizing liquid is atomized using an atomizing device, and the atomized products generated by the atomizing device are collected using a collection device. The mass of the target component in the atomized product was obtained using gas chromatography. The consumption of standard atomizing fluid is obtained, and the consumption mass of the target component is calculated based on the consumption of standard atomizing fluid and the initial concentration of the target component in the standard atomizing fluid. The atomization efficiency of the target component is calculated based on the mass of the target component consumed and the mass of the target component in the atomized product.
[0033] In this application, the standard nebulizer contains a target component with a known initial concentration. The nebulization efficiency of the nebulizer is measured based on the mass change of the target component in the standard nebulizer before and after nebulization. The method for determining nebulization efficiency based on gas chromatography can accurately measure the absolute release amount of a specific component in the nebulized product, thus providing precise data support for the research and development and improvement of nebulizers. Furthermore, because quantitative analysis using gas chromatography is used instead of traditional physical weighing, systematic errors of traditional methods are eliminated, improving the accuracy of the measurement.
[0034] In some embodiments, the atomization efficiency of the target component in the standard atomizing fluid can be calculated using the following formula:
[0035] Where W is the atomization efficiency; M is the mass of the target component in the atomized product; m is the consumption of the standard atomizing liquid; and N is the initial concentration of the target component in the standard atomizing liquid.
[0036] In some embodiments, the target components in the standard atomizing fluid include one or more of alkaloids, cooling agents, flavoring agents, stabilizers, and solvents.
[0037] In some embodiments, the alkaloids may be selected from one or more of the following: nicotine, mesmin, cotinine, neonicotinoids.
[0038] In some embodiments, the nicotine substance is selected from at least one of the following: nicotine, nicotine derivatives. Preferably, the nicotine derivative is a nicotine salt.
[0039] In some embodiments, the nicotine salt is selected from one or more of the following: nicotine benzoate, nicotine lactate, and nicotine acetylpropionate.
[0040] In some embodiments, the cooling agent is selected from one or more of the following: WS-23 (N,2,3-trimethyl-2-isopropylbutyramide), WS-3 (ethylmenthaneformamide), menthol, menthyl lactate, menthone glycerol ketal, and borneol.
[0041] In some embodiments, the flavoring agent is selected from one or more of the following: methyl anthranilate, γ-undecyl lactone, limonene, malic acid, allyl cyclohexylpropionate, isoamyl acetate, butyl acetate, ethyl butyrate, leaf alcohol, linalool, hexanoic acid, vanillin, cinnamaldehyde, and ethyl maltol.
[0042] In some embodiments, the solvent is selected from one or more of the following: propylene glycol, glycerol.
[0043] In some embodiments, the stabilizer is benzoic acid.
[0044] In some embodiments, the standard nebulizer does not contain an internal standard. For example, the standard nebulizer does not contain alkanes. For example, alkanes include methane, ethane, propane, n-butane, n-pentane, n-hexane, n-decane, dodecane, etc.
[0045] For example, a standard nebulizer contains known concentrations of the following components: propylene glycol, glycerin, benzoic acid, nicotine, leaf alcohol, linalool, menthol, limonene, hexanoic acid, butyl acetate, isoamyl acetate, allyl cyclohexylpropionate, γ-undecyl lactone, methyl anthranilate, WS-23, WS-3, vanillin, and ethyl maltol.
[0046] See Figure 1 In the embodiments of this application, the collection device includes a Cambridge filter and a collection bottle, wherein the atomized products are collected by passing through the Cambridge filter and the collection bottle in sequence.
[0047] In some embodiments, the collection bottle contains a collection solution. Exemplarily, the collection solution may be selected from one or more of the following: ethanol, methanol, isopropanol, ethyl acetate, and dichloromethane. As an example, the collection solution is ethanol.
[0048] Cambridge filters effectively intercept particulate matter (such as propylene glycol, glycerin, nicotine, etc.) in atomized products, while the collection bottle can capture volatile components (such as butyl acetate, isoamyl acetate, etc.). Compared with the Cambridge filter-only collection method in related technologies, it can capture more atomized product components.
[0049] In some embodiments, obtaining the mass of the target component in the atomized product using gas chromatography includes: Prepare a series of standard solutions of the target component with different concentrations, inject the standard solutions into gas chromatography, and obtain a standard working curve, where the horizontal axis is "concentration" and the vertical axis is "response value"; The atomized product was prepared into a test sample, and the analytical result response value of the target component in the atomized product was obtained by gas chromatography. The analytical result response value of the target component in the atomized product was then substituted into the standard working curve to obtain the concentration of the target component in the atomized product. The mass of the target component in the atomized product is calculated based on the concentration of the target component in the atomized product and the volume of the collecting liquid.
[0050] In some embodiments, four or more standard solutions of different concentrations may be prepared, for example, four, five, six, seven, eight, nine or ten standard solutions of different concentrations may be prepared.
[0051] It is understood that standard working curves can be prepared by using gas chromatography to analyze multiple standard solutions of known different concentrations using methods known to those skilled in the art.
[0052] In some embodiments, the response value is peak area or peak height. For example, the x-axis of the standard working curve is "concentration" and the y-axis is "peak area".
[0053] In some embodiments, preparing the atomized product into a test sample includes: Wipe the condensate in the collection device and the condensate at the connection between the Cambridge filter and the collection bottle using absorbent material. The collected liquid after collecting the atomized products in the collection bottle was used to extract the wiped adsorbent material and Cambridge filter, and then shaken and filtered. The filtrate was used as the test sample.
[0054] It should be noted that by directly extracting the atomized condensate from the atomized product in the collection bottle, the absorbent liquid is used to extract the condensate from the wiped adsorbent material and the Cambridge filter, resulting in only one test sample to be analyzed, making the operation simple.
[0055] In some embodiments, the adsorbent material may be a Cambridge filter, filter paper, activated carbon, or nonwoven fabric.
[0056] In some embodiments of this application, the method further includes calculating the total atomization efficiency of the standard atomizing liquid based on the sum of the masses of each target component in the atomized product and the amount of standard atomizing liquid consumed.
[0057] For example, the total atomization efficiency X of a standard atomizing fluid can be calculated using the following formula:
[0058] Where X is the total atomization efficiency; SUM(M) is the sum of the masses of each target component in the atomized product; and m is the consumption of standard atomizing liquid.
[0059] In some embodiments, the standard atomizing fluid, by total mass, comprises the following components: 39 wt% propylene glycol; 40 wt% glycerin; 2 wt% benzoic acid; 2 wt% nicotine; 1 wt% leaf alcohol; 1 wt% linalool; 2 wt% menthol; 1 wt% limonene; 1 wt% hexanoic acid; 1 wt% butyl acetate; 1 wt% isoamyl acetate; 1 wt% allyl cyclohexylpropionate; 1 wt% γ-undecyl lactone; 1 wt% methyl anthranilate; 2 wt% WS-23; 2 wt% WS-3; 1 wt% vanillin; and 1 wt% ethyl maltol.
[0060] In some embodiments, the method for determining the atomization efficiency of an atomizing device further includes filling a standard atomizing liquid into the atomizing device for atomization.
[0061] The method described in this application involves plotting standard working curves for standard solutions of known concentrations using gas chromatography, analyzing the atomized products using gas chromatography, and substituting the analytical results of the target component in the atomized products into the standard working curves to accurately obtain the mass of the target component in the atomized products. Based on the calculated mass of the target component in a small-volume standard atomized liquid, the atomization efficiency of the target component in the atomized products can be accurately measured. This method allows for precise calculation of atomization efficiency, providing accurate data support for the research and development and improvement of atomization devices.
[0062] To make the embodiments of this disclosure easier to understand, the present application will be described in detail below with reference to the embodiments. These embodiments are for illustrative purposes only and are not limited to the scope of application of the present application.
[0063] Unless otherwise specified, the specific operations and processing methods or conditions not described in the following embodiments are conventional methods in the art or are performed in accordance with the techniques or conditions described in the literature in the art or in accordance with the product manual.

The solvent in this standard atomizing liquid is propylene glycol and glycerin, the nicotine-like substance is nicotine, the stabilizer is benzoic acid, the cooling agents are WS-23, WS-3, and menthol, and the flavoring agents are methyl anthranilate, γ-undecyl lactone, limonene, allyl cyclohexylpropionate, isoamyl acetate, butyl acetate, leaf alcohol, linalool, hexanoic acid, vanillin, and ethyl maltol.
[0065] Table 1 Standard Atomizing Fluid Formulation
[0066] Methods for determining atomization efficiency The atomization efficiency of the atomizing device is determined by the following steps: (1) Use a pipette to fill 1.8 mL of the above-mentioned standard nebulizer with known concentration (initial concentration) into two nebulizers A and B respectively, and measure the weight G1 of the nebulizer filled with nebulizer.
[0067] (2) Connect the atomizing device and the collecting device to the suction machine, draw 100 puffs, and use the collecting device to collect the atomized products of the standard atomizing liquid.
[0068] The smoking machine is set with the suction parameters according to the information in Table 2. The collection device consists of a Cambridge filter and a collection bottle, wherein the collection bottle contains 20 mL of ethanol, and the atomized products are collected by passing through the Cambridge filter and the collection bottle in sequence.
[0069] (3) After aspiration is complete, place the Cambridge filter from the collection device into a 100 mL Erlenmeyer flask. Take another half of a clean Cambridge filter and wipe the condensate from the atomized product at the collection device and connecting tube. Place the wiped Cambridge filter into the aforementioned 100 mL Erlenmeyer flask. Transfer 20 mL of ethanol from the collection flask into the aforementioned 100 mL Erlenmeyer flask. Shake the Erlenmeyer flask at 200 rpm for 20 minutes, then filter it through a 0.45 μm filter membrane. Use the filtrate as the test sample to be analyzed.
[0070] (4) After the suction is completed, measure the weight G2 of the atomizing device, and obtain the weight reduction of the atomizing device through G1-G2, that is, the consumption of standard atomizing liquid.
[0071] Repeat the above method to aspirate four parallel samples.
[0072] In addition, the nebulization efficiency of control group A' was tested using the same method as group A. The difference was that the comparative test A' used a traditional collection method with a single Cambridge filter, and the weight change of the Cambridge filter before and after aspiration was recorded. (5) Take 200 μL, 400 μL, 600 μL, 800 μL, and 1000 μL of standard solution respectively, and dilute them to 1 mL with ethanol. Prepare standard solutions with the components and concentrations shown in Table 3. Analyze the standard solutions of different concentrations using gas chromatography and the operating conditions in Table 4. Establish a standard working curve with the peak area of each component as the abscissa and the concentration as the x-axis. (6) Use gas chromatography to analyze the test sample, measure the peak area of each component in the test sample, and substitute it into the standard working curve to calculate the concentration and mass of each component in the test sample.
[0073] (7) Based on the calculated mass of each component in the test sample, the consumption of the standard nebulizer, and the initial concentration of each component in the standard nebulizer, the nebulization efficiency of each component in the standard nebulizer is calculated according to the following formula:
[0074] Where W is the atomization efficiency (%), M is the mass of each component in the atomized product (mg), m is the consumption of the standard atomizing solution (mg), and N is the initial concentration of each component in the standard atomizing solution (%).

[0076] Table 3 Standard working solutions of different concentrations
[0077] Table 4 Operating conditions for gas chromatography
[0078] Calculation method 1. Mass of each component in the atomized product M = C × V The mass (mg) of each component in the M-atomized product is shown in Table 6; The concentrations of each component in the C-atomized product, mg / mL (obtained by gas chromatography); V - Add 20 mL of ethanol. 2. Calculation of atomization efficiency of each component in the atomized product
[0079] The atomization efficiency of each component in the W-atomized product, % is shown in Table 7. M - Mass of each component in the atomized product, mg; m - The consumption of standard nebulizer fluid for 100 aspirations, in mg, is shown in Table 5. The concentrations of each component in the standard atomizing solution, % are shown in Table 1.
[0080] 3. Calculation of the overall atomization efficiency of atomized products
[0081] The total atomization efficiency of X-atomized products, %, is shown in Table 7; SUM(M) - Total mass of all components of the atomized product, mg; m - Standard nebulizer fluid consumption for 100 aspirations, mg, as shown in Table 5; The peak area of each component was measured, and the concentration of each component in the atomized product was obtained according to the standard working curve. The atomization efficiency of each component of each atomizing device was calculated according to the formula, as shown in Table 7 below.
[0082] 4. Calculation of total atomization efficiency using the traditional weight reduction method
[0083] X' - Total atomization efficiency of the traditional weight reduction method, % is shown in Table 8; SUM (m) - Standard atomizing fluid consumption, g; M', - Weight gain of a single Cambridge filter, g, as shown in Table 5; Table 5. Consumption of standard nebulizer fluid (g / 100 mouths)

[0087]
[0088]
[0089] Table 8 Calculation results of atomization efficiency using the traditional weight reduction method
[0090] As shown in the table above, the RSD of parallel samples in both batches A and B is ≤3%, indicating that the laboratory repeatability and stability of nebulizers A and B are good. Furthermore, regarding the nebulization efficiency of each component, compared with the control group A', nebulizer A exhibits higher nebulization efficiency for each component, particularly for volatile components such as butyl acetate and isoamyl acetate. This is because the method of this application can better capture the nebulized products. Similarly, for the same reason, compared with the control group A', the nebulization efficiency of other components such as linalool, vanillin, and ethyl maltol is also improved by 10-20%. Likewise, the method of this application can better capture the nebulized products; the total nebulization efficiency (SUM value, approximately 93%) of group A in Table 7 is better than that of group A' in Table 7 (SUM value, approximately 86%). Therefore, the gas chromatography method of this application provides results closer to the true values. In addition, limonene is easily oxidized during the suction process, which may be the reason for its lower nebulization efficiency. In summary, traditional weight reduction methods only provide a total change value and cannot distinguish the actual release of each target component in the atomized product. Furthermore, they are easily affected by factors such as residual condensate and ambient humidity, resulting in low accuracy and poor repeatability. This application establishes a standard working curve (concentration on the x-axis, response value on the y-axis) for the target components using gas chromatography, directly determining the absolute mass of each target component in the atomized product. This is a quantitative method based on instrumental analysis, rather than indirect calculation using physical weighing, thus improving measurement accuracy. Additionally, the gas chromatography method used in this application clearly shows significant differences in atomization efficiency among different components (see Table 7). Researchers can use this information to accurately pinpoint the performance shortcomings of the atomization device, thereby enabling targeted improvements and greatly enhancing research efficiency and the effectiveness of improvement directions.
[0091] The above examples illustrate the present invention only to aid in understanding it and are not intended to limit the scope of the invention. Those skilled in the art can make various simple deductions, modifications, or substitutions based on the ideas of this invention.
