Spex CertiPrep® Assurance® Grade Quality Control Standard 21, 100 µg/mL

Mixed multi-element standard for AA & ICP
  • Diluted in 5% HNO3/tr. Tartaric Acid/tr. HF
  • Use standard to check spectral interferences
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.

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

Chemicals sold by Cole-Parmer are not intended for and should not be (i) used for medical, surgical or other patient oriented applications, or (ii) combined with any food product or ingested in any form.
