Solvent
Perchloroethylene, Freon-113, S-316
Hexane, Pentane, Vertrel MCA
Hexane, Pentane, Vertrel MCA
Component Measured
Measures all hydrocarbons
Measures hydrocarbons with a boiling point higher than the solvent - volatile hydrocarbons will be evaporated along with the solvent.

Typical Applications
• Oil in Water/Wastewater • Oil in Produced Water • Fats, Oil & Grease (FOG in Wastewater Discharges • TPH in Soil • Samples with Light-End Volatile Components
• Oil in Water/Wastewater • Oil in Produced Water • Fats, Oil & Grease (FOG in Wastewater Discharges • TPH in Soil
• Very High Levels of Oil in Water • TPH in Soil
Other
Solvents are heavier than water and require a separatory funnel or inverted vial with a septa cap to collect a solvent sample.
Solvents are lighter than water and solvent sample can be collected from the top of the container.
