ABSTRACT:
A photometric detector is used to detect the presence of organic solvent vapors in the air. The detector need only be exposed to the air in the area to be tested. The optical density, i.e. darkness of the color of the detector determines the cumulative amount of solvent vapor exposure and the rate at which the dark color develops determines the concentration of solvent vapors in the air. This method can be used to quickly and easily test for harmful levels of toxic organic solvent vapors in the workplace or elsewhere.
