This test method is a standard titrimetric procedure used to measure total hardness and calcium hardness in water, both expressed as mg/L of calcium carbonate (CaCO₃). Hardness is primarily due to the presence of magnesium (Mg²⁺) ions.

This test method is a rapid, enzyme-based method for determining the heterotrophic plate count in water samples, which measures the concentration of viable, culturable heterotrophic bacteria.
This test method is a colorimetric test method for measuring hexavalent chromium (Cr⁶⁺) in water samples. This method is based on the formation of a colored complex between hexavalent chromium and a specific reagent, allowing sensitive and selective detection.
This test method is a standardized analytical procedure for the determination of common inorganic ions in water samples using ion chromatography (IC). It is widely used for monitoring drinking water, wastewater, and environmental samples for regulatory compliance and water quality assessment. This test method can quantify bromide, chloride, fluoride, nitrate as N, nitrate+nitrite as N,… Continue reading Ion Chromatography [Non-Preserved]

This test method describes the enzyme-substrate-based detection of total coliforms and Escherichia coli in drinking water, surface water, and wastewater using the Colilert® test. This method is based on defined substrate technology, where specific enzymes produced by coliforms and E. coli react with added substrates to produce color and fluorescence, allowing for easy detection and… Continue reading Coliform / E.coli [Quanti-Tray (18 hr)]
