The BGI PQ200-FRM Sampler incorporates BGI's pioneering technology to meet the requirements for ambient particulate sampling dictated by the U.S.
Environmental Protection Agency.

This includes the design of novel PM10, PM2.5 and PM1 Inlets, Volumetric sample flow rate control, data logging and software for report and data processing.

The sampler is based upon the BGI PQ family of ambient particulate samplers and has demonstrated its use since 1997 in a multitude of domestic and international sampling scenarios. Most recently the introduction of the BGI miniPM Inlet, the PQ200 can be operated at sampling sites as high as 15,000 feet (4572meters) elevation.

The PQ200 – FRM Sampler meets and exceeds the US EPA requirements for manual ambient particulate sampling according to 40CFR Part53. BGI cooperated with the EPA in 1996 to provide design and parts of the PQ100 sampler that later became design and performance specifications for PM2.5 FRM sampling.

BGI was pleased to provide the following:


  • Ambient Temperature and Filter Temperature Testing
  • PM10 Inlet Design
  • Prototyped the EPA PM2.5 WINS Impactor
  • New EPA Class II Equivalent Method

Alternative to the WINS VSCC-Very Sharp Cut Cyclone
