Method for simultaneously determining multiple inorganic elements in cigarette liquid of electronic cigarette

Abstract

Provided is a method for simultaneously determining multiple inorganic elements in cigarette liquid of an electronic cigarette. The content of chrome, nickel, arsenic, cadmium and lead in the cigarette liquid of the electronic cigarette is simultaneously determined through an inductively coupled plasma mass spectrometry method. The method comprises the steps that determining instruments and materials are prepared; a sample solution is prepared; ICP-MS analysis conditions are determined; a standard curve is drawn; the result is calculated. According to the method, high sensitivity, good stability and high accuracy are achieved, and the five inorganic elements including chrome, nickel, arsenic, cadmium and lead can be fast and simultaneously determined.

Description

technical field [0001] The invention relates to the technical field of electronic cigarette liquid detection, in particular to a method for measuring the contents of chromium, nickel, arsenic, cadmium and lead in electronic cigarette liquid. Background technique [0002] An electronic cigarette is an electronic device that converts the electronic cigarette solution into smoke through an atomizer, and delivers nicotine and other substances to the respiratory system. Chromium, nickel, arsenic, cadmium, lead and other elements are harmful to the human body. During the process of smoking e-cigarettes, the chromium, nickel, arsenic, cadmium, lead and other inorganic elements contained in e-cigarette liquid will also be Smoke enters the human body directly from the respiratory tract. In order to objectively and comprehensively evaluate the safety of e-cigarettes, it is necessary to accurately determine the contents of chromium, nickel, arsenic, cadmium, and lead contained in e-ci...

AI Technical Summary

Problems solved by technology

[0003] For the determination of inorganic elements, traditional determination methods such as spectrophotometry, atomic absorption method, etc., have cumbersome process, long analysis period and low sensitivity.

The content of five inorganic elements such as chromium, nickel, arsenic, cadmium, and lead contained in e-cigarette liquid is relatively low, and most of them belong to the range of trace or ultra-trace. The above traditional detection methods cannot meet the requirements of these trace elements. Simultaneous quantitative detection of
