Eco-efficient oil-in-water testing according to the all-new ASTM D8193

CFC-free measurement of TPH and TOG in water and soil with sub-ppm precision

eralytics industry leading oil-in-water and oil-in-soil tester ERACHECK ECO is the only high-precision IR-analyzers on the market which is fully compliant to the newly published ASTM standard D8193 and further complies with the industries strict limits and regulations when testing oil-in-water.

Measurement according to ASTM D8193

ASTM D8193 combines the inherent advantages of IR methods like a fast and highly precise measurement with the CFC-free and low-cost solvent cyclohexane offering highest precision even for the measurement of Total Petroleum Hydrocarbons (TPH) and Total Oil and Grease (TOG) with sub-ppm precision
(method detection limit MDL of 0.5 mg/L). It covers a total measuring range of 0.5 to 1000 mg/L for TOG as well as for TPH.

Easy Measurement, Fast results

For the measurement ERACHECK ECO needs an amount of 900 ml water/50 ml solvent extraction. With its portable and rugged stand-alone design the measurement is very easy to carry out, no special skills are required and the results are available very fast. Furthermore, the fully automated measurement enables the use of eralytics’ 10-position autosampler for even higher sample throughput.


eralytics oil-in-water testers are mainly used on drilling platforms and oil fields and have many application fields:  the quality control of industrial process & waste water, reinjection water, upstream oil recovery monitoring, environmental monitoring of soil and water and layer monitoring during oil drilling.

With eralytics’ ERACHECK ECO and ASTM D8193, the industry is provided a new system for highly precise and environmentally friendly monitoring of oil and grease in discharge and wastewater applications. With the portable ERACHECK ECO measurements according to this advanced standard are made extremely easy, fast and highly reliable.
