Method for rapidly detecting photoinitiator in cigarette paper

Abstract

The invention discloses a method for rapidly detecting a photoinitiator in cigarette paper. According to the method, the 18 photoinitiators in the cigarette paper are detected by adopting an in-situ mass spectrometry detection method, and the 18 photoinitiator components in the cigarette paper can be rapidly detected without any pretreatment process on the cigarette paper. The method can be used for detecting the photoinitiator in a paper sample with a complex matrix, the sensitivity for detecting the photoinitiator is high, the detected detection limit and quantitation limit are far smaller than numerical values detected by a traditional gas chromatography-mass spectrometry method, the detected detection limit (LOD) is 0.002-0.045 mg / m<2>, and the detected quantitation limit (LOQ) is 0.006-0.15 mg / m<2>; the detection time is short, and high-throughput detection can be carried out; the matrix effect is small, and actual complex samples can be detected; and the requirements of modern product quality safety management and control on rapid detection are met.

Description

technical field [0001] The invention relates to a method for detecting harmful components in cigarette paper, in particular to a method for rapidly and efficiently detecting 18 kinds of photoinitiators in cigarette paper by using an in-situ mass spectrometry detection method, and belongs to the field of analyzing harmful components in cigarette paper . Background technique [0002] Cigarette paper is an indispensable and important part of the production of cigarette products, and its role is particularly important in the process of new product development, reduction of tar release, and reduction of harmful substances, which will directly affect the quality and production cost of cigarette products. [0003] Photoinitiator, also known as photocuring agent, is a kind of compound that can absorb energy of a certain wavelength in the ultraviolet or visible light region to generate free radicals, cations, etc., thereby initiating monomer polymerization, crosslinking and curing.

Problems solved by technology

[0008] When traditional detection methods are used for qualitative or quantitative detection of photoinitiators in cigarette paper, due to the influence of complex matrices, the analyte needs to undergo complicated pretreatment work before ionization, including paper sample shredding, soaking, extraction, shaking , centrifugation and other steps, and then use separation techniques such as gas chromatography or liquid chromatography to separate the components of the analyte before subsequent mass spectrometry detection, which usually takes several hours or even more time, consuming a lot of manpower, solvents and time
