    Article Title: Method for evaluating ion mobility spectrometers for trace detection of fentanyl and fentanyl-related substances
    Article Snippet: Continuing efforts to combat the opioid crisis in the U.S. require technologies that can detect the presence of fentanyl and fentanyl-related substances for multiple applications, including law enforcement and border protection.. Ion mobility spectrometry (IMS) technologies have a potential role here, and agencies will require robust methods to evaluate instrument performance for what are very challenging detection requirements.. A suite of commercial instruments configured for general drug and/or explosives detection was used to determine baseline performance for detection of fentanyl and 15 fentanyl-related substances to guide the development of a method.
