| titleOfInvention | Matrix Match correction-headspace gas chromatography measures the method for menthol content in the fine filter stick of vinegar |
| abstract | The present invention relates to the method that Matrix Match correction-headspace gas chromatography measures menthol content in the fine filter stick of vinegar, step is as follows: 1) mark liquid, standard reserving solution, standard working solution in preparation; 2) sample pre-treatments: after Cigarette sample separates pipe tobacco and paper, filter tip is placed in 20mL ml headspace bottle, adds interior mark liquid, sample introduction after gland packing; 3) sample determination, adopts Agilent headspace gas chromatography instrument; 4) quantitative and qualitative analysis: use standard items retention time and list to mark sample introduction qualitative, the chromatogram of blank solution, standard solution, actual sample solution; System's inner mark method ration, menthol and interior target peak area ratio y and concentration ratio x drawing standard working curve, obtain corresponding retention time, linear equation, detection limit and detectability.Present invention employs headspace sampling, sample pre-treatments is simple and easy to robotization.The method has simply, fast, accurately, robotization and the advantage such as applied widely. |
