| titleOfInvention | Method for determining volatile and semi-volatile components in cut tobacco based on HS-SPME-GC-MS/MS |
| abstract | The invention relates to a method for determining volatile and semi-volatile components in tobacco shreds based on HS-SPME-GC-MS/MS, belonging to the technical field of analytical chemistry. Taking a plurality of cigarette samples, discarding filter sticks, cutting, taking tobacco shreds, freezing at-80 ℃ for 28-32min, taking out and crushing into tobacco powder; taking naphthalene as an internal standard, weighing 0.5g of tobacco powder, putting the tobacco powder into a headspace bottle, adding 1mL of saturated sodium chloride solution, adding 30uL of acetone solution of 6 mu g/mL of naphthalene, quickly covering the bottle cap, detecting by adopting HS-SPME-GC-MS/MS, and quantifying by using an internal standard method. The method is based on HS-SPME-GC-MS/MS to measure the volatile and semi-volatile components in the cut tobacco, has simple sample pretreatment and accurate quantification, and is relatively comprehensive in analysis of the volatile and semi-volatile components in the cut tobacco, and easy to popularize and apply. |
