Kitagawa Detector Tubes offer fast quantification of hundreds of gases. Used with the Kitagawa piston style pump with click stops for accurate sampling.
Gas detector tubes change colors when chemical reagnets filled in a glass tube react with sampled target gas through the tube. The stain created is proportional in length to the concentration of the target gas. Concentration is read directly off the printed scale on the tube. Kitagawa offers about 250 kinds of tubes to measure about 400 different kinds of tubes and ranges.
Kitagawa Detector Tubes - 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 gaschromatographic analysis. Useful for sampling organic solvent vapors.
Kitagawa Detector Tubes - Silica-gel tube. 801 is designed for sampling organic solvents in environmental air. Particularly suited for polar solvents such as Methanol and Acetone which cannot be sufficiently adsorbed onto charcoal. Organic solvent vapor is adsorbed onto the silica gel while passing through the tube. Adsorbed solvent is recovered with a desorption solvent followed by gaschromatographic analysis. When sample air corresponding to 60 to 80 & of the amount causing breakthrough is passed, the color begins to change from blue to pink by the moisture from the silica gel side predicting breakthrough.
