Product Detail
High Quality Exposure Assessment...
The ChemPass Personal Sampling System provides high quality samples to determine exposure to particulate matter in different size fractions, as well as other species. The sampler has a modular design for exchanging different sampling elements, and uses a battery-powered pump that maintains a consistent flow rate. The unit samples particulate and gaseous species simultaneously when equipped with a passive sampler.
The performance of the system's PM-2.5 and PM-10 sampling devices, as well as the optional gas denuders and passive samplers have been characterized by the Harvard School of Public Health.
System Configurations
The ChemPass system comes in two main forms:
ChemPass Multi-Component Sampling System In this configuration, users can sample particulate matter for mass and species on up to four filters simultaneously. The addition of two passive samplers permits the assessment of average nitrogen dioxide (NO2), sulfur dioxide (SO2) and ozone (O3) concentrations.
ChemPass Single-Component Sampling System In this configuration, a PM-2.5 or PM-10 sampler containing a 37 mm diameter collection filter is connected directly to a pump operating at 4 l/min. The sampler can be worn either in an individual's breathing zone, or as an indoor environmental sampler.
