In order to establish the analytical method of high boiling air pollutants by gas chromatography, a new method was investigated. Concentration tube was 10 mm φ× 50 cm glass tube packed with 33% wt. silicone grease coated on C-22, and its concentrating efficiency was tested for many compounds, with which the optimum size of the tube was decided. It was confirmed that 1/50 ppm sample was detected from 40 l of air.
Injection tube to gas chromatograph was glass U-tube having a sillicone rubber stopper instead of a usual glass cock, and could be operated at 200°C. With these apparatus, high boiling pollutants such as furfural, nitrobenzene, phenol, cresol etc. were quantitatively analyzed.
This investigation was carried out as a part of the total analysis of air pollutants.
