  • 800B CHARCOAL TUBE (NIOSH-TYPE)

    • Applications: Industrial hygiene
    • Quantity: 20 tubes per box or 50 tubes per box
    •  Note: The charcoal tube is for sampling organic solvent vapours in air, primarily for use in industrial hygiene. This tube conforms to NIOSH requirements.
     
  • 801 SILICA-GEL TUBE

    • 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.
     
  • 810 DNPH-TREATED SILICA GEL SORBENT TUBE

    • Applications: Industrial hygiene; indoor air quality
    • Quantity: 20 tubes per box
    •  Note: Ideal for analysis by High Performance Liquid Chromatography (HPLC). This special sorbent tube contains silica gel crystals treated with DNPH, to collect Formaldehyde, MEK and other Aldehydes and Ketones in indoor and industrial atmospheres, when used with an air sampling pump. Benefits: 1. Stable, high performance analysis. 2. Determine low concentration quantity with low sampling volume. 3. High sampling volume. 4. No break-through from coexisting Aldehydes. 5. Identical condition can be applied for all sampling, from low to high concentration. 6. Ozone Scrubber (tube no. 820) removes 1ppm O3.
