WS-CRDS for Fenceline Pollution Monitoring

Every possible source of air pollution is subject to increasing regulation either for worker safety, to maintain air quality for nearby residents, and/or as part of larger (national and international) pollution reduction strategies and protocols. This requires the ability to monitor these pollutants at key field locations, including along pipelines, at factory perimeters and even along rooflines. A specific example is to monitor the roof space in aluminum smelting plants. Here, HF (hydrogen fluoride) is a corrosive, highly toxic, direct byproduct released from the reduction cells that must be actively filtered from the plant headspace.

Picarro WS-CRDS analyzers are well suited to these applications because of their ability to measure such gases at ppt levels and beyond. With no moving parts, and high resistance to corrosion, they can operate in unmanned remote monitoring locations for months at a time with no need for recalibration or any other maintenance. WS-CRDS can also play a key role in more complex chemical pollutants. In the case of organic molecules for example, including carcinogenic aromatics, our WS-CRDS CO2 and CO2 isotope analyzers can be used in conjunction with controlled combustion for TOC (total organic carbon) analysis.
