InfraCal 2 Oil in Water Analysers

Jun 20 2018 Read 1494 Times

The InfraCal 2 Oil in Water Analysers quickly and accurately measure TOG (total oil & grease), FOG (fats, oil and grease) and TPH (total petroleum hydrocarbons) in produced water, industrial wastewater and soil. InfraCal 2 analysers have become the petrochemical industry standard ensuring oil content levels in produced water, drill cuttings or soil are below the regulated limit. Results can be obtained in under 15 minutes, avoiding long wait time for lab results.

The InfraCal 2 Analysers are often used for industrial wastewater and water entering public water treatment plants. This simplified procedure for monitoring FOG discharges to help customers avoid fines or regulators to catch high FOG discharges that can result in sanitary sewer overflows (SSOs). In most cases, treatment plants are forced to wait for days or even weeks before receiving off-site laboratory results.

The InfraCal 2 Analysers allow for TPH (Total Petroleum Hydrocarbons) in soil testing at remediation sites such as leaking underground storage tanks, frac water holding ponds, produced water evaporation ponds or oil spills. Site managers can avoid having costly soil remediation equipment sit idle while waiting for off-site lab results.

The InfraCal 2 Analysers are stand-alone fixed filter infrared instruments that give results that are comparable to EPA 1664 and ISO 9377-2 and comply with ASTM D7066, EPA 413.2 and 418.1.

The InfraCal 2 ATR-SP is recommended for measuring oil in water, TPH in soil or FOG in wastewater concentration levels when using hexane, pentane or Vertrel MCA as the extracting solvent. The analyser is equipped with a built-in cubic zirconia horizontal attenuated total reflection (HATR) stainless steel sample stage.

The InfraCal 2 TRANS-SP is recommended for measuring oil in water, TPH in soil or FOG in wastewater concentration levels using the traditional EPA methods 413.2 and 418.1 or ASTM method D7066-04 and Freon-113, hydrocarbon-free grade of perchloroethylene, AK-225, S-316 or other spectroscopic infrared transparent solvent as the extracting solvent. Since the extract is deposited into a 10 mm quartz cuvette cell with Teflon stopper, light end volatile components are retained for measurement.
