Abstract

The invention discloses a method for screening chemical risk substances such as nitrofuran antibiotics in toiletries. The method comprises (1) establishing an accurate mass database and a mass spectral database of compounds to be detected, (2) pre-treating a toiletry sample through extraction, centrifugation, purification and filtration, and carrying out ultrahigh-pressure liquid chromatography-quadrupole-electrostatic field orbitrap high resolution mass spectrometry analysis detection on the sample solution, and (3) comparing and analyzing the test result in the step (2) and the built accurate mass database and mass spectral database in the step (1) and carrying out nitrofuran antibiotic chemical risk substance nitrofuran antibiotic screening. The method has high accuracy, strong specificity and high sensitivity and can be applied to daily detection and quality control of the toiletries.

Description

technical field [0001] The invention relates to a screening method for chemical substances, in particular to a chemical risk of nitrofuran antibiotics in toiletries based on ultra-high pressure liquid chromatography-quadrupole-electrostatic field orbitrap high-resolution mass spectrometry Substance screening methods. Background technique [0002] 1. Chemical risk substances in toiletries have potential harmful effects on consumers' personal health. [0003] From the very beginning of its birth, toiletries have provided protection for people's pursuit of a clean, healthy and fashionable life. With the continuous development and progress of society, people's pursuit of a clean, healthy and fashionable lifestyle has also been continuously upgraded, thus driving the development of toiletries. The industry has stepped into the fast lane of development and upgrading. At present, there are a wide variety of products in the cleaning and care products market, and functional, subdiv...
