The Cooper Environmental Services’ Xact 640 is a multi-metals continuous emissions monitoring system designed to simultaneously collect and analyse selected metals in samples from stack emissions. The Xact 640 system uses reel-to-reel filter tape sampling and nondestructive energy dispersive X-ray fluorescence (EDXRF) analysis to monitor stack hazardous air pollutant (HAP) metal emissions. An isokinetic sub-sample of stack gas is taken from the stilling chamber and drawn through a chemically reactive filter tape. Vapor phase metals, including mercury (Hg), are deposited along with the particulate matter (PM) on the filter tape.
Cooper Environmental Services (CES) Xact 625i is designed for high time resolution multi-metals monitoring of ambient air. The system uses reel-to-reel filter tape sampling and non-destructive energy dispersive X-ray fluorescence (EDXRF) analysis. The Xact 625i includes the Automated Data Analysis Plotting Toolset (ADAPT), which interprets the collected data and automatically generates intuitive, visual reports based on collected metal concentration and wind data.
