| titleOfInvention | Analysis method capable of simultaneously splitting characteristic nitrosamine chiral molecules of tobacco |
| abstract | The invention discloses a method capable of simultaneously splitting characteristic nitrosamine chiral molecules of tobacco. According to the method, two analysis columns are arranged in a gas chromatography thermal energy analyzer, one is a chiral chromatographic column, and the other one is a medium polar chromatographic column. During the analysis process, the medium polar chromatographic column can separate NNN from NAB and NAT, so the step of high performance liquid chromatography (HPLC) separation can be saved. Because the HPLC separation has the disadvantages that the operation is tedious, the analysis time is long, and the sample detection limit is influenced by the sample loss, the provided method has the advantages of good splitting effect and high accuracy. The provided method can be used to analyze the chiral composition of characteristic nitrosamine of tobacco, provides reference for the research on nitrosamine composition, and provides technical support for the research on the harmfulness of different chiral molecules of NAB and NAT. |
