SILICA-GEL TUBEProduct Code: 801
- Applications: Industrial hygiene
- Quantity: 10 tubes per box
- Note: 801 is designed for sampling organic solvents in environmental air, particularly for polar solvents such as Methanol and Acetone which cannot be sufficiently adsorbed onto charcoal tube no. 800B. Organic solvent vapour is adsorbed onto the silica gel, whilst passing through the tube. Adsorbed solvent is recovered with a desorption solvent, followed by gas chromatographic analysis, and the tube will change from blue to pink.
