Oil In Water/Soil Testing Portable, Rugged Infrared Analyzer


The InfraCal 2 ATR-SP is recommended for measuring oil in water, TPH in soil/drilling waste or FOG in wastewater using the traditional EPA methods 413.2 and 418.1 or ASTM method D7066-04.  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 analysis takes less than 10 minutes and is accurate down to 0.3 ppm oil in water.


With over 3,500 oil and grease monitors in worldwide use today, InfraCal 2 analyzers, originally developed by Wilks, have become a standard for the petrochemical industry. These essential tools ensure that oil content levels are below the regulated limit in water, drill cuttings, and soil. The InfraCal 2 provides real-time results for all operators needing to monitor oil in water.


Produced water in offshore oil wells presents particular challenges to wastewater treatment systems. In order to ensure oil levels in the water are under the regulatory limit before discharge, it is important to do regular testing. Infrared is a widely accepted oil content measurement and the Wilks Infrared technology has been considered an industry standard for this application for over 20 years.


The InfraCal2 Analyzer gives results in less than 15 minutes and has a reputation for the rugged durability required in the off-shore environment. The sampling requires a few simple steps that can be performed by non-technical personnel. The water is mixed with the extraction solvent, shaken, and then presented to the InfraCal 2 Analyzer for measurement. Since the extract is deposited into a 10 mm quartz cuvette cell with Teflon stopper the light end volatile components are retained for measurement.


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 12 hours continuous use.

Benefits Features
Sub-ppm Detection Reads down to 0.1ppm (+/-0.1ppm) for analysis that requires sub-ppm level of oil in water
Internal Data Storage Data storage including each measurement tagged with analyst, location and date/time information, and password protected instrument settings
Export Directly to your PC via USB or a Flash Drive
Touch Screen Display The touch screen display allows a simple set up for quick operation along with an easy calibration wizard.
Internal Battery The internal battery pack allows for portability and up to 12 hours continuous use.
Multi-Language Interface  English, Spanish, French, Arabic
Password Protected Settings Calibration and data are password protected to avoid accidental deletion
Multiple Calibrations A multitude of calibrations can be stored allowing the InfraCal to be moved to different locations without the need to recalibrate after initial calibration at a particular location
No need for Installation/Commissioning The InfraCal 2 is a portable analyzer, weighing less than 5 lbs. with a 6 in. square foot print, requiring no installation or commissioning, little to no routine maintenance or recalibration.
Minimal Consumables The analysis requires little to no consumables making the cost-per-test minimal.


The InfraCal 2 Model ATR-SP & TRANS-SP can be ordered with various factory calibrations. They are available with a single or multiple calibrations. Calibration of the analyzer enables it to directly display oil/grease concentration levels in parts per million (ppm) or milligram/kg.


Factory Calibration by Spectro Scientific
Spectro Scientific can provide the InfraCal 2 Model ATR-SP with a factory calibration using the calibration standards, prepared by a certified laboratory, listed below available for purchase. This prepares the analyzer for immediate use once received by the customer. Factory calibrations are available for water and soil. Please specify which at the time you order your InfraCal Analyzer. This option is strongly recommended for international customers, as well as those US customers who do not require a certified calibration or do not wish to calibrate the analyzer themselves.
