[A simple method for measuring cleaning solvent in air by gas detector tube for ethyl acetate].
A simple method for measuring cleaning solvent in air by gas detector tube for ethyl acetate was evaluated with regard to basic performance such as sensitivity, precision, discolor tone and effect of temperature. Satisfactory results were obtained with regard to sensitivity, precision, discolor tone in the indicator and stability of discolored length. Range of measurable concentration by the present method was about 25-800 mg/m3. It was found necessary in the present method to make temperature correction. It was concluded from these results that the present method is useful for measuring cleaning solvent in air. However, positive effect on discolored length was found by vapor of toluene and ethyl acetate when they coexisted. No effect on discolored length was found by vapor of acetone, methanol or trichloroethylene.
