The commercial SPME-HPLC interface is investigated to improve the analysis of Allium volatiles. Volatiles trapped by liquid nitrogen were previously transferred to RP-HPLC by a classical injection. In this work we compare the results obtained with classical injection and SPME used in headspace mode. This SPME-HPLC interface can be used when it is important to spare the sample, but thiosulfinates are partially degraded.
研究了商业固相微萃取-高效液相色谱接口，以改善对葱属挥发物的分析。先前使用经典进样法将液氮捕获的挥发物转移到反相高效液相色谱中。在这项工作中，我们比较了经典进样和固相微萃取在顶空模式下获得的结果。当需要节省样品但硫代亚磺酸盐部分降解时，可以使用这种固相微萃取-高效液相色谱接口。
