SPME-HPLC analysis of Allium lacrymatory factor and thiosulfinates.
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.
