InfraCal Analyzers are portable, infrared designs for fast, easy measurement of drilling mud hydrocarbons or oil in water.
They measure oil content in produced water as well as for onshore and offshore drill cuttings oil measurements. While water samples typically have hydrocarbon levels in parts-per-million - drilling cuttings can be in the 1 to 10% range.
Both InfraCal TOG/TPH Model HATR-T2 and newest InfraCal 2 Model ATR-SP can be configured with horizontal ATR sample stages. Hexane, pentane, or cyclohexane is used as the extraction solvent for 0.3 to 1000-ppm oil in water levels.
