便携式质谱仪环境采样有可能允许现场处理法医证据，并在日常执法活动中作为一种灵活的调查工具。然而，证据数据的潜在法律的影响要求从业人员酌情确保合法和道德的使用。在此，实际和理论上的使用情况下，在交通管制站的调查，使用纸喷雾电离质谱（PSI-MS）的便携式，坚固耐用的仪器，以证明执法人员的现场实用程序，特别是在提示“可能的原因”搜索车辆。具体应用包括检测和识别汽车表面上作为表面残留物的痕量违禁品，在存在潜在指纹的情况下，以及与掺假饮料和电子烟液体等新兴证据类型结合使用。此外，美国目前的状况。S.对搜查和扣押法进行了审查，以便从该技术的全部分析潜力中辨别出推定的法律的使用模式。反过来，这些研究可以帮助预先确定在警务活动中实地部署类似仪器的解释性和法律的影响。
Ambient sampling, portable MS systems have the potential to allow field processing of forensic evidence, as well as serve as a flexible investigative tool during routine law enforcement activities. However, the underlying legal implications of evidentiary data require the discretion of practitioners to ensure both lawful and ethical usage. Herein, practical and theoretical usage scenarios in traffic control stops are investigated using paper spray ionization-mass spectrometry (PSI-MS) on a portable, ruggedized instrument to demonstrate the field utility for law enforcement personnel, particularly in prompting "probable cause"searching of vehicles. Specific applications include the detection and identification of trace level contraband found as surface residues on automotive surfaces, in the presence of latent fingerprints, and in conjunction with emerging evidence types like adulterated beverages and electronic cigarette liquids. In addition, the current state of U. S. search and seizure law is examined in an effort to discern the presumed legal usage modes from the full analytical potential of the technique. These studies, in turn, can assist in predetermining the investigatory and legal impacts of field deployment of similar instrumentation in policing activities.
