CHEMetrics offers test kits employing the Caustic Titrant with pH indicator method to deliver sensitivity and accuracy within two minutes or less. Based on CHEMetrics patented Self-Filling Reagent Ampoule technology. Premixed. Premeasured. Precise. Each kit contains 30 tests.
The Caustic Titrant with pH Indicator Method
CHEMetrics' carbon dioxide test kits employ a sodium hydroxide titrant and phenolphthalein indicator. Results are expressed as ppm (mg/l) CO2.

Dissolved carbon dioxide (CO2) is naturally present as a result of animal respiration, the decay of organic matter, and the decomposition of certain minerals. It is the major source of acidity in unpolluted water samples. Surface waters typically contain less than 10 ppm (mg/l) dissolved CO2, while ground waters, particularly if deep, may contain several hundred ppm (mg/l).
