Liquid Chromatography/Mass Spectrometry A New Technique for Water Recovery System Testing

LiquidChromatogry/Mass Spectrometry (LC/MS) can improve Freedom water recovery systems testing by providing analytical information about non-volatile organic contaminants not amenable to conventional analytic techniques. A preliminary liquid chromatography method has been developed for organic acids in human urine. Using this method over twenty organic acids and related compounds can be resolved. Some of these compounds have not been reported previously from Environmental Control and Life Support System hardware testing.
