Portable Oil-in-Water Testing with ERACHECK X: Xtra RUGGED, Xtra FAST, Xtra ACCURATE

Sep 14 2021

The oil-in-water analyser ERACHECK X is eralytics latest product innovation. It is the first analyser based on our new portable and easy-to-operate instrument platform, convincing with a rugged aluminum housing with most compact dimensions, still offering a large color touch screen and a state-of-the-art built-in industry PC.

ERACHECK X is a high-end dual-beam non-dispersive IR spectrometer for the highly accurate measurement of oil-in-water. Based on the inexpensive and environmentally friendly CFC-free solvent, cyclohexane, ERACHECK X measures TOG, TPH, and FOG in water in full compliance with ASTM D8193 with sub-ppm precision, offering excellent correlation to EPA 1664, ISO 9377, and OSPAR.

The simplified extraction procedure is performed in a few steps, requiring minimum glassware and easy cleaning. The fully automated measurement of the extract takes only 2 minutes. Results are displayed on the large full-color touch screen and can be exported via USB directly to a flash drive or PC for LIMS.

Unlike gravimetric methods, ASTM D8193 does not require the evaporation of the solvent, eliminating the risk of light ends getting lost during the measurements. This leads to significantly better accuracy and precision (r = 0.25 mg/L) over a wide measuring range (0 – 3000 mg/L).

Compared to GC methods that do not detect fractions eluting outside the defined time window, with ASTM D8193 a more complete fraction of extracted hydrocarbons is measured, and this much faster and easier.

Its ruggedness and reliability make ERACHECK X the perfect solution for fast on-site compliance testing in harsh ambient conditions like the daily work on oil drilling platforms and as a portable field tester for wastewater professionals.
