Detailed Specs

CES’s Xact 640 system uses reel-to-reel (RTR) filter tape sampling and nondestructive X-ray fluorescence (XRF) analysis to monitor stack 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.
