Portable Infrared Analyzer Meets EPA Guidelines

A unique portable infrared instrument, the InfracCal TOG/TPH Analyzer, Model HATR-T2, has been developed that follows recent EPA guidelines for discharges of oily wastes from facilities that produce, maintain, or rebuild metal products and machinery (MP&M). The instrument uses hexane to extract the oil and grease from effluent samples. In the new effluent limitation guidelines, the EPA lists oil and grease as "hexane extractable material." Because hexane contains hydrocarbons, it must be evaporated so as not to interfere with the infrared hydrocarbon measurement of oil and grease. Since the InfraCal TOG/TPH Analyzer measures the "hexane extractable material" and uses an evaporation process, it will closely match the EPA hexane/gravimetric method 1664. Operators of pretreatment systems can quickly assess their system's efficiency and can see how it functions under heavy loads, while also avoiding discharging effluent above the regulatory limit.
