Micro-Gas Chromatographs (micro-GC) have the potential of providing a fieldable device that could 1) identify chemical threats in a battlefield, 2) provide assessment of warfighter health status, chemical exposure, stress level, and hydration, but we need better detectors if this potential is to… More

The Lunar Exploration Analysis Group (LEAG) has placed a high priority on determining the nature, distribution and transport of volatiles on the moon. The objective of this proposal is to create chip scale gas chromatographs for lunar exploration. Under DARPA support, Cbana has created a new… More

The objective of this proposal is to create new gas chromatographs (GCs) for contaminant monitoring in spacecraft air that do not require any reagents or special carrier gases. Under DARPA support, Cbana has created a new class of microGCs that are smaller than ever before and yet show performance… More

Based on the successful result of the developed micro-FID that was achieved in the Phase I, we propose to integrate a micro-gas analyzer and an optimized micro-FID to obtain the highest signal to noise ratio with a minimum usage of hydrogen for a portable

The objective of this project is to evaluate the feasibility of using some newly discovered materials, water-stable metal-organic frameworks (MOF), as filters for pollutants common in indoor air. By way of background, recent Defense Advanced Research Projects Agency (DARPA)-supported work from… More

Based on the successful separation of 20 compounds using a 1 m coated microcolumn in Phase I, we propose to design a new micro-gas chromatograph (microGC) system to separate and detect of all contaminants listed in NASAs "Spacecraft Maximum Allowable Concentrations for Airborne Contaminants… More
