Abstract

THE PROPOSED SEPARATOR PROVIDES A NOVEL METHOD FOR REMOVAL OF INORGANIC CARBON (IC) FROM SOLUTION PRIOR TO ORGANIC CARBON ANALYSIS. IT IS SUITED FOR EXTENDED OPERATION IN MICROGRAVITY, AS IT DOES NOT REQUIRE THE ADDITION OF LIQUID REAGENTS NOR PURGE GASES FOR INORGANIC CARBON REMOVAL. THE DEVICE CONSISTS OF A CO2 PERMEABLE MEMBRANE DEGASSER CONTAINING A SOLID-PHASE ACIDIC MATERIAL. THE DEVICE WILL BE DESIGNED FOR INTEGRATION WITH PROTOTYPE FLIGHT WATER QUALITY MONITOR HARDWARE. THE DEVICE FUNCTIONS TO REMOVE DISSOLVED GAS FROM SAMPLE STREAMS PRIOR TO ANALYSIS USING IR, UV AND OTHER METHODS OF DETECTION.
