Assurance® Grade multi-element drinking water pollutant standards for AA & ICP.

Standards may be diluted in the same matrix as specified; however, caution must be exercised in the choice of the source for your diluents. Diluting the matrix may cause some standards to precipitate. Also, an impure or unknown diluent turns your standard into an unknown. We recommend using only SPEX CertiPrep Matrix Blanks when diluting your standards.

These standards are for use with procedures for compliance monitoring of drinking water and for analysis of ground and surface water where determination of the drinking water contamination levels are required.
