Product Overview
Xact® 640 Multi-Metals Continuous Emissions Monitor
Cooper Environmental’s Xact® 640 is the first Multi-Metals Continuous Emissions Monitor to be proven successful for accurately measuring elemental concentrations in smoke stacks by capturing and measuring both particulate and vapor phase metals.
The Xact® 640 system uses reel-to-reel filter tape sampling and nondestructive X-ray fluorescence (XRF) analysis to monitor stack hazardous air pollutant (HAP) metal emissions. An isokinetic sub-sample of stack gas goes into the stilling chamber and then drawn through a chemically reactive filter tape. Vapor phase metals, including mercury, are deposited along with particulate-phase metals on the filter tape.
In 2007, the US EPA recognized the Xact® CEMS as an outstanding achievement in innovative clean air technology with a clean air excellence Award. In addition, the EPA approved the Xact® 640 as an alternative method for periodic Method 29 testing, feed stream analysis, and monitoring emissions during plant operation.
