This proposal concerns the design, development and test of a new instrument for the point detection, monitoring and alarm of chemical agents under battlefield conditions. this new instrument is the trandem ion mobility spectrometer which is a dual mobility spectrometer. the conventional ims is at… More

A miniature, specialized, flight-qualified ion mobility spectrometer (ims) will be designed, built and delivered to identify and quantitate organic volatile effluents from a gas chromatograph (gc) at concentrations of 10(-14) moles per second. in phase i, both water and non-water based ion-molecule… More

For flight experiments in low earth orbits and planetary missions, an innovative electrode structure is proposed to obtain a metastable helium ionization detector of active volume down to a fraction of a microliter for use with microbore and microchannel gas chromatographs. Such a small detector… More
