The document discusses the development of a handheld high-pressure mass spectrometry (HPMS) platform, specifically the MX908, designed for use in field applications by military, law enforcement, and first responders. The device uses a fast-switching dual-polarity APCI (Atmospheric Pressure Chemical Ionization) source, enabling it to perform trace detection in both vapor and thermal desorption modes, with detection limits down to parts-per-billion (ppbv) in vapor mode and nanogram levels on swabs. The MX908 can analyze a wide range of threats, including explosives, narcotics, chemical warfare agents, and relevant precursors, all from a single sample. Its ability to operate at higher pressures (up to 10 Torr) eliminates the need for costly and bulky vacuum pumps, making it more portable and power-efficient. The system is capable of rapid analysis with a broad mass range (m/z ~50-550) and can detect multiple targets without switching samples or polarities. Key applications include the detection of drugs, explosives like PETN and RDX, and toxic chemicals such as sarin and VX, with further refinement and field testing underway.
