A field portable mass spectrometer system comprising a sample collector and a sample transporter. The sample transporter interfaces with the sample collector to receive sample deposits thereon. The system further comprises a time of flight (TOF) mass spectrometer. The time of flight mass spectrometer has a sealable opening that receives the sample transported via the sample transporter in an extraction region of the mass spectrometer. The system further comprises a control unit that processes a time series output by the mass spectrometer for a received sample and identifies one or more agents contained in the sample.

Portable time-of-flight mass spectrometer system

An expandable sensor array including at least one expandable member movable between an unexpanded stowed state and an expanded deployed state and a plurality of sensors interconnected with the at least one inflatable member and operatively connected to form a sensor array.
