The InfraCal Model 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. Measurement data obtained with this analyzer will correlate to EPA Method 1664 as both procedures are based on evaporation techniques and measuring the residual oil and grease. The analyzer is equipped with a built-in cubic zirconia horizontal attenuated total reflection (HATR) stainless steel sample stage.   The InfraCal 2 ATR-SP is a direct replacement for the original InfraCal HATR-T2 used worldwide for the determination of TOG/TPH in water and soil.

  • Minimum Detection Limit Water: 0.3 ppm
  • Minimum Detection Limit Soil: 3 ppm
  • Method Compares: EPA 1164 & ISO 9377-2
  • Solvents: Hexane, pentane, cyclohexane & Vertrel MCA

Highlights

As offshore oil wells age, the increase of produced water challenges wastewater treatment systems.  In order to ensure oil levels in the water are under the regulatory limit, it is important to do regular testing.  Infrared analysis has been used for off-shore oil in water measurements for over 45 years.  Infrared is an accepted oil content measurement as it is least affected by changes in produced water composition.

For industrial pretreatment of wastewater and public water treatment plants a simplified procedure for monitoring FOG discharges can avoid fines, sanitary sewer overflows (SSOs) and give on-site results in less than 15 minutes rather than waiting days or weeks for an off-site laboratory result.

The InfraCal 2 has added features such as touch screen display, data storage and transfer, a multi-language interface and password protected settings.  The internal battery pack allows for portability and up to 6 hours continuous use.

Operating Principle

The InfraCal 2 ATR-SP for measuring total oil and grease and total petroleum hydrocarbons in water and soil makes use of the fact that hydrocarbons such as oil and grease can be extracted from water or soil through the use of an appropriate solvent and extraction procedure.  The extracted hydrocarbons absorb infrared energy at a specific wavelength and the amount of energy absorbed is proportional to the concentration of oil and grease in the solvent.  The analyzer can be calibrated to read out directly in the desired units.

Calibrations 

The InfraCal 2 Model ATR-SP is available with a single or multiple calibrations. Analysis results of total oil and grease & total petroleum hydrocarbon concentration levels are displayed in parts per million (ppm) or milligram/kg.
