| titleOfInvention | A kind of UPLC-IE method is used to measure the method for main carbonyl compounds in cigarette shreds |
| abstract | The invention belongs to the physical and chemical inspection technical field of cigarette shreds, the assay method of main carbonyl compounds (formaldehyde, acetaldehyde, acetone, acrylic aldehyde, propionic aldehyde, crotonic aldehyde, 2-butanone, butyraldehyde) in a kind of cigarette shreds, the method is to utilize the main carbonyl compounds in acetic acid aqueous solution extraction cigarette shreds and by after derivatization treatment, and recycling Ultra Performance Liquid Chromatography isocratic elution method (UPLC IE) analyzes the main carbonyl compounds in cigarette shreds.Using the content of main carbonyl compounds in the inventive method detection cigarette shreds, the most effectively, pre-treatment is simple, and average relative standard's deviation is less than 7%, and the average recovery rate of each index is between 92% ~ 101%.Have quick and precisely, highly sensitive and reproducible advantage. |
