3 Date Passed: 13-Jul-2010 Balance: Expiration date of the unopened ampule stored at the recommended storage condition. 2A Purity is determined by one or more of the following techniques: GC/FID, HPLC, GC/ECD, GC/MS. Value is rounded to the nearest whole number. Chemical identity is confirmed using GC/MS. See data pack or contact provider 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. Manufactured under Restek's ISO 9001:2008 Registered Quality System Certificate #FM 80397
