This model is recommended for measuring TOG, TPH or FOG levels using the traditional EPA methods 413.2 and 418.1 and Freon-113, spectroscopic hydrocarbon-free grade of perchloroethylene, AK-225, S-316 or other transparent solvent as the extracting solvent. Since the extract is deposited into a 10mm quartz cuvette cell with Teflon stopper, light-end volatile components are retained for measurement. Accurate down to 2 ppm.

This model uses specially-designed reusable IR sample plates with sapphire windows, having a 100 microliter sample injection capacity. Suited for measuring higher levels of TOG or TPH in water or soil samples extracted with hexane, pentane or Vertrel MCA. Light-end volatile components will be lost in the evaporation process.

InfraCal TOG/TPH Analyzer, Model HATR-T2
Used in WERF Fats, Oil and Grease (FOG) Study

The Water Environment Research Foundation (WERF) sponsored an extensive study to evaluate the performance of different grease interceptor designs and their affect on wastewater discharges. The InfraCal IR Platform Analyzer, Model HATR-T2 was used to measure the concentration levels of fats, oil and grease (FOG) in wastewater leaving the interceptors. The complete study has been released by WERF (www.werf.org) in a report titled “Assessment of Grease Interceptor Performance” (Ducoste, Kenner, Groninger and Holt, 2008)

The InfraCal Cuvette Holder Analyzer, Model CVH The InfraCal Cuvette Holder Analyzer, Model CVH was one of the infrared instruments used to develop ASTM Standard Test Method D 7066--04 --04

The ASTM has approved a new standard test method for measuring total oil and grease (TOG) and total petroleum hydrocarbon (TPH) concentration levels in water and soil. ASTM Method D 7066-04 covers the use of dimer/trimer of chlorotrifluoroethylene (s-316) for analysis of recoverable oil and grease and nonpolar material by infrared determination.
This ASTM method approves S-316 as a replacement solvent for Freon for this analysis and replaces ASTM Method D 3921. With the publication of this method, the ASTM officially approved the use of S-316 as a replacement solvent for Freon when measuring TOG and TPH in water and soil.
The extraction procedure detailed in the new ASTM method is basically the same as outlined in US EPA Methods 413.2 and 418.1, but using S-316 as the extracting solvent instead of Freon. ASTM Method D 7066-04 is idea for measuring volatile constituents.

Model CVH Allows On--Site Analysis to Meet New European Regulations

New European regulations governing the measurement of oil-in-water, a 15% hydrocarbon emission reduction target and Hydrocarbon Trading have all heightened the importance of monitoring oil concentration levels in water. The Oil Pollution Prevention and Control (OPPC) Regulations prohibit the discharge of oil into the seaunless it is in accordance with the permit issued to cover the discharge. In support of OPPC, the UK DTI (Department of Trade and Industry) has provided industry with technical guidance on suitable methods for the sampling and analysis of produced water and other samples containing hydrocarbons. An OSPAR modified version of the ISO 9377-2 GC-FID method (Gas Chromatography and Flame Ionization Detection) has been adopted as the reference method effective January 1, 2007. Since GCFID analysis is generally done in a laboratory and not onsite, the DTI guidelines permit the use of other methods that have a crude oil specific validation against the GC-FID. Many operators have chosen the InfraCal TOG/TPH Analyzer for use at their facilities because it is a portable device providing faster results at a much lower cost.
