7. Select the testing and documentation that best meet your requirements:
Gravimetric:
Product supplied with the gravimetric records detailing exact amount of each raw material used, purity of each material used, total volume prepared, calculated concentration, and a unique lot number.
Qualitative:
A single sample withdrawn from the packaged units is tested by the appropriate technique to verify mixture composition. Product supplied with a certificate of composition showing a chromatogram of the standard with each peak identified, raw material purity, and gravimetric concentration.
Quantitative:
A sample of the packaged unit is analyzed in triplicate and the peak areas are statistically compared to a previous lot (if available) or a second, independently prepared lot. Unless otherwise specified, the acceptance criteria are as follows: The coefficient of variation (CV) will not exceed 5% for the peak areas of the triplicate injections of the sample. The percent difference of the average peak areas of the sample compared to the previous or second lot will not exceed 10%. A detailed data pack is available at www.restek.com containing gravimetric documentation, all quantitative assay raw data, and statistics. All raw material purity and identification results are available upon request.

Restek's quality policy is to use the highest purity raw materials available; however, not all materials will be free of impurities. Please specify any compounds that cannot be present in your formulation. We will do our best to ensure that these compounds are not present in the raw materials used to manufacture your standard. Please also list any additional compounds or special requirements not previously identified. Thank you.

11. Notes and comments:
  • Visit www.restek.com/iso to learn more about our ISO quality credentials and view our certificates (including scopes of accreditation).
  • Restek uses the highest purity raw materials available and will make a weight correction on any compound with a purity less than 99%.
  • Concentration is based upon gravimetric preparation using either a balance whose calibration has been verified daily using NIST traceable weights, and/or dilutions with Class A glassware.
  • All concentrations under 0.001% are based on serial dilution calculations using class A glassware and are not verified by testing.
