CFC-free measurements on site: the ERACHECK goes below 1 ppm
The advent of Quantum Cascade Lasers (QCLs) as a new, powerful mid-IR light source has opened the possibility to develop a fast and
ecologically friendly method for quantifying oil in production water and wastewater. After extracting the hydrocarbons with cyclohexane or
cyclopentane instead of ozone depleting freon, precise concentrations can be determined by means of mid-IR laser spectroscopy.
The ERACHECK oil in water analyser was developed by QuantaRed Technologies GmbH, Austria (www.quantared.com), in cooperation with
EralyticsTM GmbH, Austria (www.eralytics.com). The benchtop instrument is easy to use (touch screen operation) and allows CFC free
measurements with high precision and sensitivity (sub-ppm concentrations). Due to its portability and a measurement time of only 2 minutes
the ERACHECK may be used on-site as well as in mobile or stationary laboratories.
