Sampling media, namely, chemicals in the nature of sorbents held inside glass tubes and stainless steel tubes, all for facilitating the use of aforementioned air sampling pumps for the collection of hazardous air contaminants; Sampling media, namely, chemically treated cellulose and chemically treated sorbents held inside small plastic housings with multiple holes through which air contaminants diffuse, all for the collection of hazardous air contaminants

Air sampling pumps for providing airflow in collecting hazardous air contaminants onto and into sampling media

Sampling media, namely, paper filters and plastic filters held inside plastic cassettes and restrictive size-selective metal samplers and plastic samplers that separate contaminants by size, all for facilitating the use of aforementioned air sampling pumps for the collection of hazardous air contaminants

Sampling media, namely, sample bags made of extruded plastic film, not for wrapping, into which air is pulled with aforementioned air sampling pumps to trap hazardous air contaminants, all for facilitating the use of aforementioned air sampling pumps for the collection of hazardous air contaminants
