| titleOfInvention | A kind of method for quick of tobacco leaf volatile ingredient |
| abstract | A kind of method for quick of tobacco leaf volatile ingredient, it is characterised in that：The method extracts tobacco leaf using dichloromethane, after sample after extraction is through chromatogram post separation, is shunted using the end of microplate stream control technology regulation and control chromatographic column, while into quadrupole rod time of-flight mass spectrometer（QTOF MS）And flame ionization detector（FID）Determine, realize the accurate qualitative, quantitative of tobacco leaf volatile ingredient, whole process is simple to operate, time-consuming short, can high-volume, automatic business processing sample.The present invention is completed by only needing simple solvent extraction, and consumption organic solvent is few, and whole process truly reflects the actual conditions of sample in the absence of the second order reaction problem of tobacco leaf volatile ingredient；Extract is detected using gas-chromatography quadrupole rod flight time mass spectrum/flame ion first, only needing a pin sample introduction can simultaneously obtain QTOF MS and FID spectrograms, wherein QTOF MS can accurate qualitative complex sample composition, and FID instrument can accurate quantitative analysis concentration range sample very wide, and the two spectrogram retention times are just the same. |
