A current trend in environmental sampling is the utilization of a multi-bed system. Within one tube, there are multiple layers of different sorbent materials. Different classes of chemicals are preferentially adsorbed into specific layers.
Tubes are available for either solvent or thermal desorption.
SKC currently manufactures a variety of sorbent combinations as standard items, but specialty tubes can be made for custom applications. Each tube has a flow direction arrow and unique number. For a detailed explanation, refer to the methods. Contact your SKC representative for more information.
