Cooper Environmental XACT 625i

Real Time Metals in PM Monitor

Cooper Environmental’s Xact® 625i is designed for high time resolution multi-metals monitoring of ambient air, with detection limits that rival those of laboratory analysis. The Xact® 625i comes standard with a solid-state meteorological sensor and Cooper Environmental’s proprietary ADAPT analysis package, making the instrument one of the most powerful air pollution source detection offerings in the industry.

The system uses reel-to-reel filter tape sampling and nondestructive energy dispersive X-ray fluorescence (EDXRF) analysis. The air is sampled through a low volume (16.7 l/min) particulate matter (PM) size-selective inlet and drawn through a filter tape. The resulting PM deposit is then advanced into the analysis area where the sample is analyzed by EDXRF for selected metals while the next sample is collected.

Measurement method........ Based on EPA Method IO 3.3: Determination of Metals in Ambient PM Using XRF

Key applicable elements.....Sb, As, Ba, Cd, Ca Cr, Co, Cu, Fe, Pb, Hg, Mn, Ni, Se, Ag, Sn, Ti, Tl, V, Zn, & more available

Detection limits (IF, EPA IO 3.3)1...... Metal and sample time dependent; refer to the minimum detection limit (MDL) data

Sampling and analysis times......Every 15, 30, 60, 120, 180, or 240 minutes, user defined 

Calibration stability check frequency........Automatically with each sample analyzed

Estimated recalibration frequency....Annually, when manufacturer’s operating recommendations are followed

Sample flow rate......16.7 lpm

Linearity......Correlation coefficient >0.99 

Size and weight......19” w x 20” d x 30” h 183 lbs 19 inch (483 mm) rack-mountable or tabletop

Required operating environment.....Lab environment with temperature controlled to 20±5°C (68°F)

Power requirements....120 VAC/60 Hz @ 20 amp or 220 VAC/50 Hz 10 amp circuit
