Alkalinity, Bicarbonate And Carbonate

Alkalinity, HCO3, CO3

Summary

This method measures bicarbonate (HCO3-), carbonate (CO32-) and alkalinity levels in water. Quantitation is by titration with 0.025 N H2SO4. The method has a routine detection limit of 0.1 meq/L but is capable of a method detection limit for alkalinity of 0.04 meq/L (2 mg CaCO3/L) if requested by client.

Sample must be refrigerated.  Sample should not be filtered or acidified.
Sample amount requested:  50 mL
Questions concerning limited sample size can be answered by the UC Davis Analytical Laboratory.
