CALUX is a globally recognized method for measuring dioxins.
The biological testing method, recognized worldwide and the only one in Japan to have passed the Ministry of the Environment's qualification examination and ISO 17025, is offered exclusively by Keirax. We have a proven track record both domestically and internationally across various media, including exhaust gas, ash, soil, and deposits inside furnaces. Since 2015, we have been entrusted with acceptance inspections and sampling inspections at the Osaka Bay Area Coastal Environmental Improvement Center. In addition to statutory inspections of facilities, please consider us for daily self-inspections, evaluations of renovation work, screening tests around facilities, and as a method for research and testing. Comparative testing with other parties is also possible depending on the content of your request.
Inquire About This Product
basic information
The CALUX Assay (Chemically Activated Luciferase Expression) is a technology (bioassay method) developed by the American company XDS (Xenobiotic Detection Systems International, Inc.) that obtained a patent in the United States in December 1998. It is a simple and rapid measurement method for the convenient and quick detection of dioxins (PCDDs, PCDFs, DL-PCBs). Utilizing the luminescence principle of fireflies, CALUX is a faster, cheaper, and more sensitive and high-performance testing method compared to traditional high-resolution gas chromatography-mass spectrometry.
