Preparation Note: | Description • This ampule contains a concentrate of blended gasoline from three different sources in methanol. • This PT sample is packaged as a 1.5 mL concentrate. • The solvent for this sample is methanol. • The PT sample is not preserved. Sample Preparation • Fill a 100 mL volumetric flask to volume with carbon-filtered reagent-grade water at room temperature. • Open ampule PE1798-2ML (be careful to avoid cuts on glass) and immediately withdraw 20 μL. • Quickly inject the 20 μL aliquot into the reagent water in the expanded area of the volumetric flask. • Mix the sample by inverting the flask three times only (excessive shaking results in loss of volatiles) and analyze immediately. |
