Abstract

The invention discloses a method for measuring a carbonyl compound in electronic cigarette liquid. The method comprises the following steps: preparing carbonyl compound derivative solutions at different concentration gradients by taking an acetonitrile solution of pyridine as a solvent; detecting the prepared carbonyl compound derivative solutions at different concentration gradients to obtain corresponding high-performance liquid chromatograms by utilizing high-performance liquid chromatographic instrument with an ultraviolet detector; drawing a standard working curve of carbonyl compound derivatives by taking the concentrations of the carbonyl compound derivatives in the carbonyl compound derivative solutions as the abscissa and taking the ultraviolet response integral areas of the carbonyl compound derivatives at different concentrations as the ordinate; measuring a sample solution to be measured by utilizing the high-performance liquid chromatographic instrument with the ultraviolet detector, and calculating the content of the carbonyl compound in the sample solution to be measured. The method is simple in pretreatment, convenient to operate, short in analysis time, high in sensitivity, recovery rate and precision and suitable for the measurement of the content of the carbonyl compound in the electronic cigarette liquid.

Description

1. Technical field [0001] The invention relates to a detection method, in particular to a detection method for carbonyl compounds in electronic cigarette liquid. 2. Background technology [0002] In recent years, the topic of smoking and health has been widely concerned by people, and smoking is harmful to health has been generally recognized by people. In 2005, China signed the "Framework Convention on Tobacco Control" to provide a legal basis for tobacco control. In 2012, the Chinese government issued the "China Tobacco Control Plan (2012-2015)", proposing to create a smoke-free environment and implement a comprehensive ban on smoking in public places. Electronic cigarette, also known as electronic cigarette nicotine delivery system, 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 "healing the lungs" as their promotional slogans, using the Internet as the main marketing cha...
