Abstract

A new SPME device was developed and applied for quick solventless extraction/enrichment of small molecules from complex matrices. Subsequently, the device was coupled as a transmission mode substrate to DART resulting in limits of detection in the low pg mL(-1) level in less than 3 minutes with reproducibility below 5% RSD.

摘要

开发了一种新型固相微萃取(SPME)装置,并将其应用于从复杂基质中快速无溶剂萃取/富集小分子。随后,该装置作为传输模式基质与直接实时分析(DART)联用,在不到3分钟的时间内实现了低皮克/毫升(pg mL⁻¹)水平的检测限,相对标准偏差(RSD)低于5%。
