QCL-IR Transmission Spectroscopy of Carbohydrates

Our group is pioneering the use of QCLs for the analysis of liquids. The work in this field led to the foundation of QuantaRed Technologies GmbH (QRT) in 2008 as a spin-off company of our research group. QRT has successfully introduced a new way to measure the parameter “oil-in-water” in a rapid, environmentally friendly and portable format using an instrument called ERACHECK which is commercially available through our distribution partner Eralytics GmbH. Currently it is in use in more than 15 countries on 4 continents. Recent applications of broadly tunable QCLs concern the simultaneous determination of up to 7 parameters in human sera, the use of QCLs as detectors in separation systems as well as a rapid alternative for TOC (total organic carbohydrates) measurements in clean in place (CIP) systems.
