Ideal for sampling pesticides, explosives and glycols.
The tubes combine sorbent and filter in one tube; a filter to trap aerosols and a two-section sorbent bed to adsorb vapours in one specially constructed glass tube that eliminates filter and tube sampling trains. Aerosols and vapours can be collected simultaneously. Only cleaned and verified materials are used in OVS tubes to ensure low background interference. A flow rate of 1 L/min is typically used, and the samples are extracted and analysed by gas chromatography (GC) or high performance liquid chromatography (HPLC) with detector.
The size of all the OVS tubes is 13→8 x 75 mm (Length x OD) and the tubes have open glass ends. The OVS Tube Holder (224-29V) is designed to accommodate the 13 mm diameter of SKC OVS tubes, provide a convenient clip to attach the tube in the breathing zone, and protect the tube during sampling.
it from most other adsorbents. It has unusually good physical
durability and is stable at temperatures as high as 200°C
