New Promega Water-Glo™ System combines ATP detection and bioluminescence technologies for quick, highly sensitive water quality testing
Promega Corporation’s new Water-Glo™ System offers water plant operators a rapid, highly sensitive and flexible measurement tool for monitoring microbial contamination in freshwater, process water, seawater or wastewater samples. The Water-Glo™ System, launched by Promega recently, uses bioluminescent technology to measure adenosine triphosphate or ATP, the "energy currency" of all living cells that degrades rapidly when a cell dies. Even the slightest change in ATP levels acts as an early warning system to assess the presence of live microbes and possible dangerous pathogens in water.
Water-Glo™ reagents were used in recent research by scientists at the world renowned IHE Delft Institute for Water Education based in Delft, the Netherlands demonstrating the first “direct method” of measuring ATP in seawater. The paper “ATP measurement in seawater reverse osmosis systems: Eliminating seawater matrix effects using a filtration-based method” is published in the March 2019 issue of the international journal Desalination.
ATP detection provides technicians a number of advantages compared to other methods for detecting microbes in water such as heterotrophic plate count (HPC), flow cytometry and indirect methods such as turbidity or pressure drop. Benefits include:
Promega, a leading manufacturer of reagents, leveraged the company’s expertise in bioluminescence technology developed over the last 25 years to develop the Water-Glo™ System, one of the most sensitive tools in ATP detection in the environmental and water testing industry.
Water-Glo™ Chemistry is also available as part of a fully automated system. The AppliTek EZ-ATP® Analyzer with the Water-Glo™ Chemistry provides a total solution for online microbial analysis of water samples.
