| titleOfInvention | Method for processing buccal cigarette sample and method for detecting aldehyde substances in buccal cigarette |
| abstract | The invention relates to a method for processing a buccal cigarette sample and a method for detecting aldehyde substances in buccal cigarette, belonging to the technical field of chromatographic analysis and detection of smokeless tobacco products. The invention discloses a method for processing buccal tobacco samples, which comprises the following steps: sequentially adding an acidic pH regulator, a derivatization reagent and an extracting agent into a buccal cigarette sample, uniformly mixing, standing for layering, and taking an upper organic phase as a sample to be detected; the volume of the extracting agent adopted by every 1g of buccal cigarette is 8-15 ml. The method for processing the buccal cigarette sample can accelerate the leaching of the aldehyde substances in the buccal cigarette, shorten the reaction time of the aldehyde substances in the buccal cigarette and a derivatization reagent, and simultaneously realize the extraction of the reacted product into an organic phase, thereby further shortening the analysis and detection time, reducing the loss of the aldehyde substances in the analysis and detection process and improving the accuracy of the analysis and detection. |
