Abstract:

An ultra performance liquid chromatography-triple quadrupole mass spectrometric (UPLC-MS/MS) method was developed for simultaneous separation and determination of 26 prohibited substances in commercially available masks, which contained glucocorticoid, quinolones and imidazole derivatives. The samples were dispersed in saturated sodium chloride solution and were extracted with acetonitrile. After removal of macromolecular matrix by potassium ferrocyanide and zinc acetate, the samples were purified by solid phase extraction. The binary gradient elution was performed with acetonitrile (containing 0.1% acetic acid)-0.1% acetic acid solution, and the multi-reaction monitoring was used for analysis. All the 26 compounds show a good linear relationship in their respective concentration ranges, and the correlation coefficients (r) are no less than 0.995. The limits of detection (LODs) range from 1 to 80 ng/g. The limits of quantification (LOQs) are in the range of 4-380 ng/g. The average recoveries of 26 prohibited substances in masks range from 86.4% to 115.2%. The method is simple, accurate and sensitive. It can be used for quantitative analysis of prohibited substances in commercially available masks.

Key words: ultra performance liquid chromatography-triple quadrupole mass spectrometry, mask, glucocorticoid, quinolones, imidazole derivatives
