Handheld mass spectrometer MX908 identifies traces of hazardous chemicals on site.


Fast. Sensitive. Selective.

Mobile mass spectrometer MX908

The handheld mass spectrometer MX908 detects trace quantities of chemical warfare agents, home-made explosives, hazardous chemicals, narcotics, derivatives of the fentanyl family or other priority hazmat substances directly on-site. Since these substances can be lethal even in extremely small quantities, the device increases dramatically the safety of elite responders in priority scenarios. The MX908 is characterized by stable, selective identification of smallest traces. Frequently occurring substances during on-site usage such as gasolines or after shaves do not influence the results.


The MX908 weighs just 4.3 kg, making it a true handheld and mobile solution, unlike other mass spectrometers that are bulky, heavy and not suitable for on-site use. The user interface is very easy and intuitive. With its large buttons, the device is suitable for safe operation in full protective gear. Alarms are displayed within seconds and provide immediate background information on the substance found. The MX908 operates with the innovative “high-pressure mass spectrometry” (HPMS). With an air flow rate of approx. 3 l / min, the measuring cell can be flushed completely. This ensures rapid reuse after detection, quickly enables follow-up measurements and avoids long downtime and waiting.
Thus, the high selectivity of the mass spectrometer can easily exploit its advantages over other methods.

Send results from danger zone via app

The MX908 can send analysis results directly from the hazard zone. Simply download the app, pair the MX908 mobile mass spectrometer with your smartphone or tablet via Bluetooth, and request assistance or have the hazard potential assessed by CBRN expert advisors without delay.
