A miniature mass spectrometer for hydrazine detection

A Miniature Mass Spectrometer (MMS) with a focal plane (Mattauch-Herzog) geometry has been developed at the Jet Propulsion Laboratory. The MMS has the potential to meet the NASA requirements of 10 parts per billion sensitivity for Hydrazine detection, as well as the requirements for instant response, portability, and low maintenance.

Hydrazine Detection with a Tunable Diode Laser Spectrometer

Several instruments have been developed to measure low concentrations of hydrazine but none are completely satisfactory. A brief review is presented of current instruments such as the electrochemical cell, the ion mobility spectrometer, the mass spectrometer, the gas chromatograph, and the electronic nose.
