Wilks Enterprise has developed a portable infrared instrument, the InfracCal™ TOG/TPH Analyzer, Model HATR-T2, that uses hexane to extract oil and grease from effluent samples. In the new effluent limitation guidelines governing oily waste discharges, EPA lists oil and grease as "hexane extractable material." Because hexane contains hydrocarbons, it must be evaporated off in order not to interfere with the infrared hydrocarbon measurement of oil and grease.
