ABSTRACT:
Total organic carbon (TOC) and inorganic carbon (TIC) monitoring of water is useful in determining the water quality. Conventional TOC and TIC monitoring techniques are not zero gravity compatible. The addition of microporous hydrophobic bladders in combination with a non-dispersive infrared analyzer allow for a two phase, liquid and gas, zero gravity compatible TOC monitoring technique. The non-dispersive infrared analyzer determines the quantity of carbon dioxide present in an aqueous sample after addition of acid and post oxidation. The measured carbon dioxide quantities derived from the aqueous sample are related to the TIC and TOC present in the aqueous sample, respectively.
