The Xact® 625i by Cooper Environmental is a high-resolution multi-metals monitoring system for ambient air, featuring advanced detection limits comparable to laboratory analysis. It employs solid-state meteorological sensors, real-time data analysis through its proprietary software, and non-destructive energy dispersive X-ray fluorescence for metal detection. The system is adaptable for various applications, including fence-line monitoring and source apportionment, with capabilities to measure multiple metals simultaneously and deliver immediate graphical reports.

- 1. Standard Features 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 propri- etary 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 nondestruc- tive 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 col- lected.
