Environmental samplers, as the name implies, are teams that take samples of certain compounds from the air for later analysis and determination of air quality parameters. These samplers may or may not have US EPA approval and are designed to collect a sample either in a filter or in some other medium under conditions specified by the air quality protocols of the US EPA. This sample must meet certain requirements which the instruments must consider the sample collection, ensuring that the sample is representative of the environment where it was taken. These samplers serve to collect gases and particulate material and meet all the requirements for the collection of these samples according to US EPA best practices.
