Pall Corporation, a provider of solutions to meet the critical fluid management needs, announced that it has unveiled new systems for environmental and emissions monitoring.
Pall explained that its Xact systems monitor single or multiple metals in on-stack and ambient applications such as incinerators, coal-fired power plants, smelters, cement kilns, and air quality monitoring units.
The company asserted that the Xact systems are customizable to monitor single metals, such as mercury, or multiple metals. Equipped with a micro porous filtration membrane, the Xact system utilizes nondestructive, energy-dispersive X-ray fluorescence to quantify heavy metal particles deposited on the membrane. The data produced enables the demonstration of environmental regulatory compliance, research of health effects from ambient metals, and the location of sources of metals in specific air sheds.
Officials with the company stated that Xact systems are the latest example of Pall's commitment to broadening its portfolio of environmental protection solutions. By combining their microporous membrane media with CES's (News - Alert) market-proven XRF technology, they are now able to offer customers complete systems for single or multi-metal emissions monitoring.
For emissions monitoring at the stack, Pall is now offering the Xact 640 Multi-Metal Continuous Emissions Monitoring System and the Xact 645 Continuous Mercury Monitor and for ambient atmospheric testing, the company is offering the Xact 620 Ambient (News 
- Alert) Metals Monitor.
Pall’s Xact 645 continuous mercury monitor uses reel-to-reel (RTR) filter tape sampling and nondestructive X-ray fluorescence (XRF) analysis to monitor air at the stack. Some of the benefits of this solution are: can be upgraded to measure additional elements (such as Pb, As, Cr) without extra hardware; may be used to meet 40 CFR Part 60 regulations; measures total mercury in µg/dscm; and more.
The company claimed that the Xact 640 monitor became the first multi-metal CEMS to be verified through the United State’s Environmental Protection’s (EPA) Batelle ETV program.
The Xact 620 monitoring system can be used to establish baselines for health-based standards and is capable of identifying hazardous “hot spots” around the perimeter of a facility and enables effective source apportionment and chemical mass balance comparisons. It can also correlate metals to wind speed and direction and demonstrate metal concentration variability not observable with standard federal reference methods.
