Sample Collection

There are two methods of collecting a sample for the GasID. The Thermal Desorption sample collection method involves using a sorbent tube and the thermal desorption sampling module while the Tedlar Bag method involves using a Tedlar bag and the Tedlar Bag Sampling Module. Generally, the Thermal Desorption method should be used, however, the Tedlar Bag method should be used for incidents involving high concentration environments and/or sampling of inorganic materials.

The attached document details how to obtain samples using a desorption method and a tedlar bag method.
