Spex CertiPrep® Assurance® Grade Quality Control Standard 7A

Multi-element standards for AA & ICP instrumentation
  • Quality control standards help ensure accurate and reliable results
  • Manufactured under ISO 9001, ISO/IEC 17025 and ISO 17034 compliance
Use the Quality Control Standards 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.
