Particulate matter sampler

A particulate matter sampler is an instrument for measuring particulates (solids and liquids) in air. Particulate matter (PM) is a mixture that can include both inorganic materials (e.g. carbon, metals and other chemicals from dust, smoke, soot, sea salt, or sulfates) and organic materials (e.g. bioaerosols from microbial, fungal, animal, or plant sources).

Air quality is monitored worldwide by regulatory stations. Scientists, industries, and the public are also interested in using low-cost particulate matter sensors to detect air quality locally and in real time. Some particulate matter samplers can continuously measure and report properties of particulates, while others collect samples for later analysis in a laboratory. Different types of PM samplers can measure particulate matter in terms of particle size, particle mass, particle number, particle size distribution, and particle surface area. Inertial separators may be used to eliminate particles outside of the size range that is desired to be measured.
