Thorleaf Research, Inc., develops miniaturized instrumentation for space flight and oceanographic measurements. This includes work to develop miniature GC/MS systems (in collaboration with JPL) for planetary atmosphere measurements and environmental monitoring during long duration human space flight, underwater sampling systems, and a micro-sampling probe and programmable thermal desorption/pyrolysis inlet system for in situ astrobiology-related measurements in soils and ice. Other research projects include High Pressure Micro-Sampling System for in Situ Deep Subsurface Measurements and High Pressure Atmospheric Sampling System for Venus or the Gas Giants.
