OIL IN WATER/SOIL TESTING
PORTABLE, RUGGED INFRARED ANALYZER


The InfraCal Model CVH 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. Accurate down to 2 ppm. The Model CVH was one of the instruments used to develop the ASTM method D7066 oil in water method.  

If you plan to use the Model CVH with Tetrachloroethylene (Perchloroethylene), the only Tetrachloroethylene we have found that gives consistent results is from J.T. Baker "Ultra Resi-Analyzed" Tetrachloroethylene specifically made for trace hydrocarbon analysis by IR spectroscopy. www.avantormaterials.com
