Eralytics ERACHECK ECO oil-in-water tester

ERACHECK ECO, from Eralytics, is a dual-beam, non-dispersive IR spectrometer enabling eco-efficient measurement of oil in water based on the CFC-free solvent cyclohexane. Total petroleum hydrocarbons (TPH) and total oil and grease (TOG) in water and soil are measured with sub-ppm precision and the IR analyser is fully compliant with the latest oil-in-water standard ASTM D8193.

Unlike gravimetric methods, ASTM D8193 does not require evaporation of the solvent, eliminating the risk of light ends getting lost during the measurements. Compared to GC methods that do not detect fractions eluting outside the defined time window, ASTM D8193 enables a faster, easier and more complete fraction of extracted hydrocarbons, according to the company.

The rugged and portable design of the device makes it suitable for on-site measurements even in harsh environments like oil drilling platforms.
