Problems solved by technology

If the ammonia content is too low, the strength of the smoke will decrease and the fullness will not be enough; however, excessive ammonia will produce a strong irritant, causing the smoker's throat to constrict, making people feel coughing in the nose and tongue with an unbearable pungent feeling; Therefore, ammonia plays an important role in controlling cigarette smoking
However, there are no relevant research reports

Embodiment 1

[0033] The invention discloses an ion chromatographic determination method for ammonia content in electronic cigarette smoke. The testing process is to smoke the electronic cigarette in a linear smoking machine. Use Cambridge filter and absorption bottle to capture the ammonia in the e-cigarette smoke, and use 10mmol hydrochloric acid solution as the extraction liquid to shake and extract the Cambridge filter, and 10mmol hydrochloric acid solution as the absorption liquid. Membrane filtration, injection ion chromatography analysis. Quantitative analysis was performed by external standard method.

Abstract

The invention relates to an ion chromatographic measurement method for the ammonia content in flue gas of an electronic cigarette. The method is used for measuring the ammonia content in the flue gas of the electronic cigarette. The method comprises the following steps: (1) preparing a sample solution to be measured; (2) preparing a standard working solution; (3) performing ion chromatographic analysis; (4) drawing a standard curve, and calculating a result; (5) calculating the ammonia content of the flue gas of the electronic cigarette according to a formula. According to the method, an analysis method for measuring the ammonia content of the flue gas of the electronic cigarette is established for the first time, is rapidly operated, and is simple and easy, a method for rapidly measuring the ammonia content of the flue gas of the electronic cigarette is established, and a blank in a method for measuring ammonia in the flue gas of the electronic cigarette is filled.

Description

technical field [0001] The invention relates to the technical field of pear blossom inspection of electronic cigarette products, in particular to an ion chromatography determination method for ammonia content in electronic cigarette smoke. Background technique [0002] Electronic cigarette (electrical cigarette, e-cigarette), also known as electronic nicotine delivery systems (ENDS), is a new type of nicotine intake method that looks similar to cigarettes. Over the years, e-cigarettes have used "health care", "quit smoking" and "cleaning the lungs" as their promotional slogans, with the Internet as the main marketing channel, and their sales in China have increased significantly. However, the safety of e-cigarettes has not been officially confirmed, and product quality lacks uniform standards in China. There are still few studies on the composition determination and safety assessment of electronic cigarette products, especially the composition determination in electronic ci...
