A PM10 high volume air sampler is a federal reference method (FRM) instrument designed to collect ambient particulate matter with an aerodynamic diameter of 10µm or less. This sampler uses a size selective inlet to separate out the particulate matter that is larger than 10µm, ensuring that only concentrations of PM10 are deposited onto the filter. These samplers typical operate with a flow rate between 36-60 ft³/min during a 24 hour sampling period. Constructed of high quality components and a robust anodized aluminum shelter, these instrument are well suited for all ambient sampling installations. Tisch Environmental’s PM10 high volume air samplers are designed according to the guidelines that are outlined in 40 CFR appendix J to part 50 and designated as a federal reference method sampler under designation number 0202-141.
