A multi-mission handheld mass spectrometer from 908 Devices, utilised by elite responders conducting chemical, explosive, priority drug and hazmat operations around the world. Trace-level threat detection and discriminating selectivity deliver real-time actionable intelligence in seconds. MX908 detects compounds at sensitivity levels comparable to ion mobility spectrometry (IMS). It also identifies threats at levels not much else can. The power of high-pressure mass spectrometry (HPMS) delivers unparalleled selectivity to accurately discriminate priority threats from the myriad of interferents that lead to false alarms with other technologies.
