| titleOfInvention | A kind of method of use leaching method analysed for powder essence sample |
| abstract | The present invention relates to a kind of method of use leaching method analysed for powder essence sample, including：(1) powdered flavor sample and acetone are pressed into mass volume ratio 1g:1~4ml is mixed, and is stirred 60~90 minutes, 0~4 DEG C of standing takes upper solution in 4~5 hours, is filtered, and centrifugation takes supernatant；(2) volatilize supernatant remaining 2~3ml solution naturally in fume hood, and solution is taken out, and carries out the analysis of GC MS sample introductions；(3) repeat step (1)~(2) extraction and analysis using ether, analysis result will collect twice, you can obtain sample analysis result.The sample pre-treatments mode that the present invention is used is easily operated, and the time is short, can significantly improve test efficiency, and favorable reproducibility, copy very useful to essence. |
