Sorbent Media-XAD

XAD Sorbent Media is a crucial tool for capturing airborne contaminants at inline collection points. Primarily used for the collection of particulate matter, it facilitates the sampling of substances like organophosphorous pesticides and formaldehyde. The XAD-2 resin, coated with 2-(hydroxymethyl) piperidine, enhances the media's efficacy. Calibration methods for the flow include rotameters and bubble tubes, ensuring precise measurements. This guide references key resources, including SKC Inc. and occupational safety literature, for further understanding.
