Charcoal tube

800B is designed for sampling and measurement of organic solvents in air with personal sampler for industrial hygiene (conformed to NIOSH requirements).
Sample air containing vapor of organic solvents is passed through a glass tube packed with charcoal which adsorbs the solvent. Adsorbed solvent is recovered with desorption solvent leeching followed by gas chromatographic analysis. Useful for sampling organic solvent vapors.
