Firstly, we should understand that electronic cigarettes often consist of three basic components: a cartridge, an atomizer, and a battery. Among them, the e-liquid contained in the cigarette cartridge is directly related to the physical health of the smoker.

According to relevant information, the main components of e-liquid are nicotine, propylene glycol, glycerin flavoring, and other additives. Compared to traditional cigarettes, it has fewer substances such as carbon monoxide and tar, which indeed has less harm to the human body. However, in reality, the nicotine content in electronic cigarette cartridges currently on sale has not been effectively regulated. This also means that the risk of harm to physical health caused by excessive nicotine still exists among the e-cigarette population. However, propylene glycol, as an approved food additive, is inhaled into the human lungs in the form of a gas, and its safety is also questionable.

At present, the methods for determining nicotine include chromatography, spectroscopy, potentiometry, photometry, etc. In addition, to accurately determine the content of nicotine in e-liquid, we also need to use a constant temperature and humidity chamberESDElectrostatic Tester0Waiting for laboratory instruments and equipment. In addition, to understand the specific components in e-liquid, mass spectrometry and other methods can also be used.

Secondly, the quality of atomizers and batteries in electronic cigarettes is also one of the issues we should pay attention to. The quality testing items for atomizers mainly include resistance value, airflow, smoke volume, oil leakage, and working temperature testing. The detection of battery quality is more complicated, including multiple detection items such as short circuit protection, charging protection, overcurrent, charging time, smoking timeout protection, etc. It is understood that most of these projects can be tested through automatic smoking machines and various testing machines. It should also be noted that the above-mentioned nebulizer has a similar principle to the medical nebulizer used in hospitals, but the difference is that the latter will use laser particle size analyzer testing technology to detect its drug atomization ability, which is more rigorous.

In addition to the above-mentioned instruments, gas detectors with corresponding gas detection capabilities can also detect whether harmful gases are present in electronic cigarette smoke. Someone once confirmed through a four in one gas detection test that electronic cigarette smoke does not contain hydrogen sulfide, carbon monoxide, etc. But it should be recognized that gas detectors cannot detect the true level of nicotine, the culprit that causes addiction.

Moreover, according to reports, a certain brand of electronic cigarettes in the United States has launched multiple flavors such as cream and mango, which has led to an increase in the number of American high school students trying to use electronic cigarettes75%It can be seen that this is the caseXHThe marketing strategy of teenagers using electronic cigarettes has been reversed compared to the original intention of electronic cigarettes entering the market.
