对消费者直接使用的各种化学产品中的活性成分进行了痕量和批量鉴定，并用质谱仪进行了分析。外部环境电离与能够串联质谱分析的便携式质谱仪相结合，提供了高度的化学特异性和灵敏度，并允许进行现场监测。这些实验是使用定制的便携式离子陷阱质谱仪与环境电离方法相结合进行的，这些方法包括纸喷雾、树叶喷雾和低温等离子体电离。对杀菌剂、花园化学品、空气清新剂和其他产品进行了检查。郊区草坪除草剂施药后5d在单叶上原位检测到除草剂。
Identification of active components in a variety of chemical products used directly by consumers is described at both trace and bulk levels using mass spectrometry. The combination of external ambient ionization with a portable mass spectrometer capable of tandem mass spectrometry provides high chemical specificity and sensitivity as well as allowing on-site monitoring. These experiments were done using a custom-built portable ion trap mass spectrometer in combination with the ambient ionization methods of paper spray, leaf spray, and low temperature plasma ionization. Bactericides, garden chemicals, air fresheners, and other products were examined. Herbicide applied to suburban lawns was detected in situ on single leaves 5 d after application.
