Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of electronic cigarette detection, and particularly relates to a collection device and detection analysis system for electronic cigarette atomization release. BACKGROUND

[0002] The common smoking material in electronic cigarette products is electronic cigarette oil, that is, electronic atomization liquid used in cooperation with electronic cigarettes. The electronic cigarette oil can generate mist like a cigarette through heating by an electronic cigarette atomizer and become a release in the form of an aerosol, that is, a gaseous dispersion system composed of solid or liquid particles suspended in a gaseous medium. The aerosol generated after the atomization of the electronic cigarette is the direct object of smoking for a smoker, and therefore, the harmful substances that are not conducive to human health in the aerosol, and the components that mainly reflect the sensory quality of the electronic cigarette, such as sweeteners, cooling agents, flavor substances with aromatic odor, etc., accurate detection of the content of the above components plays an important role in the evaluation and improvement of the quality of electronic cigarette products.

[0003] To detect the content of various components in the electronic cigarette atomization release, the first step is to collect the aerosol of the release. However, the aerosol of the release contains gaseous, liquid and solid substances, and the substances in different states contain acidic, alkaline and neutral compounds, and the components are complex and have great differences in properties between different components, and therefore, it is difficult to effectively, completely and non-specifically collect and adsorb the components in various forms or various properties in the aerosol.

[0004] The commonly used methods for collecting aerosols of electronic atomizers at present include: 1. Cambridge filter sheet collection; 2. Foaming type collection trap using organic or inorganic solvents; 3. Cold trap collection; 4. Electrostatic capture; 5. Tube or box type adsorption box; 6. Activated carbon adsorption, etc. Among them, the Cambridge filter sheet method is suitable for particles with a diameter greater than 0.2 μm, and is commonly used for high content substances such as nicotine, propylene glycol and glycerol; the foaming type collection trap method is commonly used for the collection of characteristic substances such as nicotine, aldehydes and ketones, and heavy metals; the cold trap collection is commonly used for the detection of volatile substances, but the cold trap equipment has a high cost and low stability; the electrostatic capture method is only limited to the detection of heavy metals; the adsorption method has less existing standards and literature, and is only used for the test of aldehydes and ketones; the activated carbon adsorption method has good adsorption of various substances in the aerosol, but has great difficulty in analysis, and even some low content substances cannot be successfully analyzed.

[0005] Meanwhile, some adsorption methods in the field of electronic cigarettes or other fields are also provided in the prior art, for example, patent CN217218166U uses activated carbon containing different pore volumes for adsorption; patents CN105842378A and CN118225931A use filter sheets for capture; and patent CN104324521A uses multiple adsorption materials including activated carbon, silica gel, etc. for elution purification. However, the above methods and the several methods mentioned above are similar in principle and effect, and do not improve the effect well.

[0006] Although there are many kinds of existing electronic atomizer aerosol test methods, the recovery rate of the substance is low during collection; and each collection is only used for testing one substance, which brings a large amount of work to the test. Therefore, a convenient and economical method and device suitable for simultaneous collection of various substances in aerosols are urgently needed. Practical new type content

In the adsorption and collection operation, the airflow generated by the electronic cigarette can enter the solid phase extraction column from the inlet end, pass through the densely packed polymeric adsorption material for adsorption, and then flow out of the solid phase extraction column from the outlet end.

[0053] Example 1

[0054] The first embodiment of the present application provides a collection device for electronic cigarette aerosol particles, which can simultaneously collect various components in the aerosol generated after the atomization of electronic cigarette oil, especially sweeteners, cooling agents and various flavor substances, and facilitate subsequent elution and reuse of analytical instruments for detection and analysis. The device is used for electronic cigarette aerosol component identification and related research work.

[0055] As shown in Figure 1 , the collection device includes a release capture unit for capturing aerosol release generated after atomization of electronic cigarette liquid mist.

[0056] Among them, the release capture unit includes a solid phase extraction column 2, please refer to Figure 1 and Figure 2 The solid phase extraction column 2 includes a hollow through columnar shell, such as a needle cylinder columnar outer tube 201, which has two opposite and open ends, which are the gas inlet end for receiving smoke and the gas outlet end for making smoke flow to the suction unit. When capturing smoke, the airflow release end of the electronic cigarette 3 is connected to the gas inlet end of the solid phase extraction column 2.

[0057] Please continue to refer to Figure 1 and Figure 2The solid phase extraction column 2 is filled with a high polymer adsorption material 202 for adsorbing and collecting aerosol release. The high polymer adsorption material 202 is tightly packed in the inner part of the columnar outer tube 201. When performing adsorption and collection, the airflow generated by the electronic cigarette can enter the solid phase extraction column 2 from the air inlet end, pass through the densely packed high polymer adsorption material, and then flow out of the solid phase extraction column 2 from the air outlet end. Optionally, to avoid interference with the components of the airflow during adsorption, the material of the outer tube 201 can be polyethylene or polypropylene.

[0058] In this embodiment, the high polymer adsorption material 2 is polyvinylbenzene.

[0061] Continuing to refer to Figure 1 and Figure 2 In order to clamp and fix the high polymer adsorption material 202, the solid phase extraction column 2 is further provided with a porous first sieve plate 203 and a second sieve plate 204.

[0064] Continue reading Figure 1 The device also includes a suction unit for inhaling electronic cigarettes, which is connected to the release collection unit mentioned above, so that the aerosol release stream generated by inhaling electronic cigarettes passes through the solid phase extraction column 2 and is adsorbed and collected by the polymer adsorbent material 202.

[0065] In one embodiment, the suction unit includes a suction machine 1, which can provide power for the suction action of the electronic cigarette and can set suction parameters including but not limited to suction frequency, suction flow rate, suction duration, number of suction ports, etc., according to experimental requirements.

[0066] Continue reading Figure 1 The smoking machine 1 has an open suction connector 4, which can be used to block the outlet end of the solid phase extraction column 2 so that the gas flow that has completed adsorption flows from the solid phase extraction column 2 to the smoking machine 1.

[0067] In one embodiment, the smoking machine 1 can be a commercially available electronic cigarette automatic smoking machine, such as the smoking machine with the manufacturer and model number Jingyao JY-JM08.

[0068] In one embodiment, during the vaping test, the e-cigarette's atomizer tank is placed horizontally downwards at a preferred angle of 45°, with the mouthpiece at its top aligned with the axis of the solid-phase extraction column 2. Optionally, to achieve the aforementioned tilt angle of the e-cigarette, the collection device may also include a clamping assembly for securing the e-cigarette 3. The clamping assembly can be a conventional clamping tool, such as a clamping stand with clips found in chemical experimental apparatus, and is not shown in the figures.

[0069] The collection device of the embodiment uses a solid phase extraction column 2 filled with polyvinyl divinyl benzene as a high polymer adsorption material 202 to adsorb and collect the aerosol release of the electronic cigarette 3. The surface of the polyvinyl divinyl benzene is bonded with pyrrolidone and a small amount of urea-based functional groups. Under the condition of a specific pore feature and a specific amount, the polyvinyl divinyl benzene can efficiently adsorb gaseous, liquid and solid substances and acidic, basic and neutral substances in the aerosol release, especially the volatile gaseous substances such as low-carbon esters and olefin terpenes in the flavor substances. The subsequent elution step has high elution efficiency, which is beneficial to the analysis and detection of various components.

[0087]

[0088] In the electronic atomizer suction test, the number of suction is 20, the oil tank of the electronic atomizer is inclined at an angle α = -45°, and the top suction nozzle is aligned with the device axis.

[0089] Specifically, the component elution in step two is specifically as follows: after the suction is completed, the adsorption column is taken down and fixed on the extraction device, and 20ml of methanol is used for elution in four times, that is, 5mL of methanol is used for elution each time, and the elution is performed in four times. After the elution is completed, all the eluate is filtered through a 0.22μm filter membrane, and the filtered solution is transferred into a 1.5mL chromatographic vial and tested on the machine.

The sweetener content in the aerosol was finally determined by calculation.

[0092] (2) Cooling agent test: The collected eluent was analyzed by gas chromatography-mass spectrometry and the various cooling agents in the collected liquid were quantified. The content of cooling agents in the aerosol was finally determined by calculation.

[0093] (3) Flavor substance test: The collected eluent was detected by gas chromatography-mass spectrometry, and the flavor substances in the collected liquid were qualitatively and semi-quantitatively determined by a semi-quantitative method.

[0095] The specific steps are as follows:

[0096] Select 3 samples of the same batch of electronic cigarette atomizers, and then... Figure 1 The electronic cigarette was connected in series with solid-phase extraction column 2 and smoking machine 1, and the inhalation parameters shown in Table 1 were used for inhalation. Aerosols from 20 puffs of 3 groups of samples were collected simultaneously. After inhalation, the solid-phase extraction was eluted four times with 20 mL of methanol. The eluents were then combined and diluted to 20 mL, mixed, and filtered through a 0.22 μm filter before being analyzed by HPLC and GC-MS. The electronic cigarette atomizer and solid-phase extraction column were accurately weighed before and after inhalation. The loss from the electronic cigarette atomizer and the collection from the adsorption device were calculated using the differential method. The overall aerosol absorption and collection results are shown in Table 2. The results of sweetener, cooling agent, and flavor substance content obtained by instrument testing are shown in Table 3.

[0098]

[0099] Table 3. Test results of aerosol components

[0100]

[0101]

[0102] From the data in Table 2, the overall trapping efficiency of the aerosol can reach more than 99%; from the data in Table 3, it can be seen that the method has good adsorption and elution effect on each component of the aerosol, and has high stability.

[0103] Comparative experiment

[0105] Select one electronic cigarette atomizer of the same batch as the above experiment, connect the electronic cigarette with the Cambridge filter collection box and the smoking machine in series, place two Cambridge filters in the Cambridge filter collection box, and carry out smoking according to the parameters shown in Table 1, and collect 20 aerosols at the same time. After the smoking is finished, extract the Cambridge filters with 20 mL of methanol, fully extract, pass through a 0.22 μm filter membrane, and then test by HPLC and GC-MS. Accurately weigh the electronic cigarette atomizer and the solid phase extraction column 2 before and after smoking, and test the content of sweeteners, cooling agents and flavor substances by instrument. The results are shown in Table 4:

[0106] Table 4 Test results of each component of aerosol collected by Cambridge filter

[0107]

[0108]

[0109] From the comparison of the data in Tables 3 and 4, it can be seen that using the adsorption device of the present application, various flavor substances in the aerosol can be better trapped, especially for low-carbon esters and terpenes in the gaseous part of the aerosol, which are volatile substances. Therefore, it can be explained that the aerosol components obtained by using the electronic cigarette collection and analysis technology have the advantages of being more comprehensive and more accurate, which can provide reliable data support for subsequent related aerosol research.
