1 Expiration date of the unopened ampule stored at the recommended storage condition is the last day of the month listed.
2A Purity and chemical identity are determined by one or more of the following techniques: GC/FID, HPLC, GC/ECD, GC/MS. Purity value is
rounded to the nearest whole number. See data pack or contact Restek for further details.
2B Compounds with a listed purity of less than 99% have been weight corrected to compensate for impurities.
2C The following types of compounds will have a listed purity of less than 99%: Aldehyde/Ketone-DNPH compounds, Bromides, Chlorides,
HCL salts, HBR salts, sulfates, hydrates, and other compounds as necessary. The listed purity is a correction factor that is equivalent
to the percentage of parent compound in the molecule. This correction factor is used to calculate the amount of compound necessary
to achieve the desired concentration of the parent compound in solution. The concentration listed on the certificate is the concentration
of the parent compound in the solution.
2D Purity of isomeric compounds is reported as the sum of the isomers. Value is rounded to the nearest whole number after summation.
3
Based upon gravimetric preparation with balance calibration verified using NIST traceable weights (seven mass levels) and/or class A
glassware used for dilutions.
4 Uncertainties determined using data for balances and glassware from measurement systems analysis methodology, raw material purity,
and, when significant, equipment tolerances or calibration results.
5A Containers are overfilled to ensure the packaged amount, as a minimum.
5B Restek supplies deactivated vials along with most standards packed in 2 mL ampules, for the handling and storage of standards. Due to space
constraints, Restek does not supply vials for larger volume ampules. Samples should be transferred into deactivated vials for handling and
storage. Restek sells DMDCS for the purpose of glassware deactivation as catalog number 31840, which includes complete instructions. Restek
will also deactivate larger volume vials from our inventory, as a custom ordered item. Contact your Restek sales or customer service
representative for details.
