Air in a working place like workshops contains thin solvent vapours, often as mixtures. It is rather difficult to analyze them quantitatively. It seems, however, to be necessary from the stand-point of occupational health to isolate and quantitatively determine each constituent, because injuriousness varies in each solvent. This paper deals with the determination of such solvent vapours by means of gas chromatography. 1. Sampling and preserving. Industrial air is sampled by a 100 ml glass injector, when piston in operated with the injector by stirring up its inner part so as to gain the possible uniform gas. The needle-attached pipe is capped with a small rubber cap, and carbowax 1500 is applied to it against gas leakage. Then the injector filled with sampled gas is being kept horizontally, until it is taken out for gas chromatography. 2. Gas chromatographic technique. First, a survey is made on the method of quantitative determination of aromatic hydrocarbons and others in the solvent. Then, the best result is obtained with gas chromatography under the following conditions. Stationary phase: 2% squalane/diasolid M (40∼60 mesh) 2 m packed column Column temperature: 80℃∼100℃ Carrier gas: Nitrogen Gas flow rate: 20∼30 ml/min Detector: Hydrogen flame ionization detector 3. Determination. After performing gas chromatography with the sampled gas, the detector response peak is measured. And then the concentration of the sampled gas is determined by reading the value of the response peak against the standard calibration curve of its equivalent gas.
