Xtra Rugged, Fast & Easy

ERACHECK X is built in a corrosion-resistant aluminum housing and has no moving parts. Its ruggedness and reliability make it the ideal solution in tough ambient conditions for the daily work on oil drilling platforms and as a portable field tester for wastewater professionals.

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.

Xtra Accurate

ERACHECK X is a high-end dual-beam non-dispersive IR spectrometer for the highly accurate measurement of oil-in-water. Based on the in-expensive and environmentally friendly CFC-free solvent, cyclohexane, it measures in full compliance with ASTM D8193, offering excellent correlation to EPA 1664, ISO 9377-2, and OSPAR. 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 a significantly better accuracy and precision (r = 0.25 mg/L) over a wide measuring range (0 – 3000 mg/L).

Measurement Procedure

• Extract the water sample with cyclohexane: typically 200 mL of water is extracted with 15 mL cyclohexane.
• Select the calibration you want to use: ASTM D8193 or FOG
• Enter the name of the sample and the name of the operator
• Press the RUN button
• Inject 5 mL pure cyclohexane for the background measurement
• Inject 3 mL of the extracted cyclohexane for the sample measurement

ERACHECK X guides you through the measurement procedure. The liquid volumes have to be entered depending on the actual volumes used for the extraction of the sample
