Assurance® Multi-Element Standards for AA & ICP
Quality Control Standards

Quality Control Standards are used to check the standard curve, the procedure for inter-element correction and other spectral interferences. These standards are carried throught the entire analytical operation of the method. If the determined concentration is not within ? 5% of 1 ?g/mL, the laboratory performance is unacceptable. The source of the problem should be identified and corrected before continuing the analysis.

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 standard.
