We offer a complete line of air monitoring products for the sampling method of your choice: active, passive and whole air samplers. Active sampling is performed by drawing air through a type of adsorbent media such as an ORBO tube, Thermal Tube, Filter or Impinger using an air pump.
Passive sampling is achieved when contaminated air enters the device by diffusing onto the adsorbent media inside the device.
A whole air sample is collected when the air is drawn into some sort of vessel (e.g. Tedlar bag, glass bulb, stainless steel "bomb" or a canister).
In addition to your media needs, we offer Air Monitoring Chemical Standards for ASTM, NIOSH, OSHA, US EPA, California Air Resources Board (CARB), European mixes, and general use Air Monitoring standards.
