4 General Reference Material Notes Expiration Notes: Expiration date valid for unopened ampul stored in compliance with the recommended conditions. Uncertainty, concentration, and expiration of the RM are based on the unopened product being stored according to the recommended condition found in the storage field. Purity Notes: Purity and/or chemical identity are determined by one or more of the following techniques: GC/FID, HPLC, GC/µECD, GC/MS, LC/MS, RI, and/or melting point. Compounds with a listed purity of less than 99% have been weight corrected to compensate for impurities and/or salts. A correction factor is used to calculate the amount of compound necessary to achieve the desired concentration of the parent compound in solution. Purity of isomeric compounds is reported as the sum of the isomers. Purity values are rounded to the nearest whole number. Uncertainty Value Notes: Uncertainties are determined using data from balances and glassware, raw material purity, and, when significant, equipment tolerances or calibration results. Manufacturing Notes: 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. Handling Notes: Samples should be transferred into deactivated vials for handling and storage. Restek supplies deactivated vials along with most standards packed in 2 ml ampules. Due to space constraints, Restek does not supply vials for larger volume ampules. Restek sells DMDCS for the purpose of glassware deactivation as catalog number 31861, 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. If any undissolved material is visible inside the ampul, sonicate the unopened ampul until the material is completely dissolved. Page 4 of 7
