The MiniVol™ portable air sampler can be configured to collect either PM2.5, PM10, or TSP samples - but only one type at a time. The MiniVol's pump draws air at 5 liters/minute through a particle size separator (impactor) and then through a 47mm filter. The 10 micron or 2.5 micron particle separation is achieved by impaction, or a TSP sample can be collected by removing the impactor(s). Gas samples can be taken simultaneously with particulate matter samples. The particulate sample is caught on the filter, which must be weighed pre- and post-exposure with a microbalance accurate to one microgram. Sampling results are reported in micrograms/cubic meter.
