| titleOfInvention | The high-performance liquid chromatogram determination method of formaldehyde and acetaldehyde in a kind of quick-fried pearl of cigarette filter |
| abstract | The present invention relates to the high-performance liquid chromatogram determination methods of formaldehyde and acetaldehyde in a kind of quick-fried pearl of cigarette filter, belong to tobacco inspection technology field.The high-performance liquid chromatogram determination method of formaldehyde and acetaldehyde in the quick-fried pearl of cigarette filter of the present invention, quick-fried pearl is crushed the following steps are included: 1) ceramic proton and the quick-fried pearl of cigarette filter are placed in acetonitrile the concussion that be vortexed, then processing is performed the derivatization, filters, obtains prepare liquid；2) prepare liquid is measured using high performance liquid chromatography.The high-performance liquid chromatogram determination method of formaldehyde and acetaldehyde in the quick-fried pearl of cigarette filter of the present invention, sample pretreatment process is simple, quick, and analysis time is greatly saved, and analyzes convenient for batch sample；Sensitivity and accuracy are high, reproducible, are suitable for the residues detection of formaldehyde and acetaldehyde in the quick-fried pearl of cigarette filter. |
