The measurement is calculated from the total carbon in a water sample, subtracting out inorganic carbon from dissolved carbon dioxide and carbonic acid salts to arrive at the TOC Count. The inch-pound units given in parentheses are for information only. With that being said, how is water quality measured and how do researchers determine the purity of water necessary for their process? Particular attention should be taken regarding the location and sequence of particular puri?

The techniques presented can help the investigator increase the accuracy of analyses performed. Ion exchange, distillation, or reverse osmosis and organic adsorption may be required prior to distillation if the purity cannot be attained by single distillation.
