| titleOfInvention | The chiral analysis of nicotine closes phase chromatographic tandem mass spectrography in a kind of tomato |
| abstract | The invention discloses a kind of chiral analysis of nicotine in tomato to close phase chromatographic tandem mass spectrography.It is characterized by: by tomato sample drying, crushing and sieving, sample is after sodium hydroxide solution infiltrates, using methyl tertiary butyl ether(MTBE) and methanol solution extraction, extract liquor is after Dispersive solid phase extraction purifies, it is connected-is closed phase chromatographic tandem analytical reagent composition using two chiral columns, using S- (-)-nicotine in areas of peak normalization method quantitative detection tomato and R- (+)-nicotine ratio.The detection method that this method provides, sample extraction purification method is simple and efficient, pollution of the sample liquid to chromatographic column can be reduced, close phase chromatographic tandem mass spectrography detection method high sensitivity, specificity is good, false positive can be excluded, analysis time is short, can satisfy the chiral analysis of nicotine in high-volume tomato sample. |
