Restek Quality Control Standard Mixture Revised, 500 µg/mL, Acetone, 1 mL/ampul

ISO/DIS 9377-4 describes a gas chromatography/flame ionization detection (GC/FID) method to analyze total petroleum hydrocarbons (TPHs) in drinking, surface, waste, and treated waste water. Previous methods used Freon extraction, which was harmful to the environment. This method uses less harmful solvents such as pentane, hexane, or cyclohexane for sample extraction.

Restek offers mixtures for ISO/DIS 9377-4 analyses. Florisil cleanup to remove polar compounds is accomplished using a 150-250µm (60/100 mesh) sample preparation column. The analytical column suggested is either an Rtx-1 or an Rtx-5 column with dimensions of 10-25m, 0.25-0.53mm ID, and 0.25-1.0µm film thickness.
