采用DART-MS(实时直接分析质谱法)建立了一种简单快速测定人工合成驱蚊化合物如DEET(避蚊胺)、BAAPE(驱蚊酯)等的方法.在常温常压下,无需对天然驱蚊产品进行任何预处理,通过比对标准品的质谱信号离子,即可快速鉴别出天然驱蚊产品中的人工添加剂.该方法大大缩短了分析时间,并且具有原位、准确且高通量的优点.
A simple and rapid method for the determination of synthetic insect repellent compounds such as DEET (DEET), BAAPE (insect repellent) and the like was established using DART-MS (real-time direct analytical mass spectrometry) Insect repellent products for any pretreatment, by comparing the standard mass spectrometry signal ions, you can quickly identify the natural insect repellent products in the artificial additives.This method greatly reduces the analysis time, and with in situ, accurate and high-throughput The advantages.
