| Abstract: | An automatic and continuous analysing device of aro- matic compounds in the ambient air has been developed. This device is composed of GO-FID, a six-way valve and a vacuum pump, which is controlled by a microprocessor in GC. Air samples were analyzed qualitatively and quantitatively by the device for three weeks, and 16 kinds of aromatic compounds such as benzene, methylbenzene etc and the changing trends of their concentrations were observed in Huhehot. |
