Online oil-in-water detection using dual-QCL spectroscopy Background: Industry proven methods for the reliable quantification of oil in water are generally based on absorption measurements. One such method (ASTM D7678) has been standardized by QuantaRed Technologies and employs a conventional extraction method using cyclohexane. (1) A defined amount of water (containing traces of oil) is sampled...

SCIENTISTS USE PHOTONICS TO MAKE WASTEWATER ECO-FRIENDLY Wastewater will soon become cleaner and less harmful to plants and animals thanks to a new, ultra-sensitive water sensor being developed by European scientists to detect tiny amounts of toxic substances with light. A new laser system to detect minute traces of toxic substances in wastewater is currently...
