EquipmentMaterials and Reagents  Ice Bath (32 – 34°F)  Grabner CCA-VPS Vapor Pressure Analyzer  Vacuum Pump  Citizen Printer (CMB-910)  2.2 – Dimethylbutane (≥ 99% purity)  Toluene Scope / Objective This procedure covers the determination of the total vapor pressure of petroleum samples using the EPA formula. This method is suitable for liquids exerting a vapor pressure between 1 and 18.6 psi @ 100°F. Note: This procedure is only valid at the time of printing.

(Holding down RUN together with ↑ or ↓ key allows scrolling through alphabet in steps of 10 letters at a time.) iv.Continue adding sample names and updating sampler position until all sample names have been entered. 17Immerse sampling tube(s) into sample(s) ensuring order corresponds to sample info entered previously. 18Press RUN button to begin measurement(s). 19Results are printed automatically as each sample analysis is completed.
