NIST works to identify, research, and document improvements to current and next-generation detection systems.  Emphasis is placed on performance characterization of mass spectrometer-based systems, front-end development for ambient mass spectrometer platforms, and optimized testing methodologies for orthogonal detection systems. Current work is focused on development of technologies for detection of emerging thereat such as inorganic oxidizers.
