To control PCDD sand PCDFs exhausted from MSW incineration plants, it is necessary to monitor these compounds. But the analytical method of them is not so easy. Chlorobenzens also chlolinated aromatic ompounds are known the same contaminations, and concentrations of them are correlated with PCDDs and PCDFs. Analysis of chlorobenzenes is easy because of the irvolatileness and high concentration levels. So we developed an automatic analyzer of chlorobenzenes for MSW incineration plants. This system was composed from GC-FID（HP-5880A）, a concentration tube peaked with Tenax GC, a 6-way valve, a 3-way valve and a vacuum pump. This analytical system was set on a incineration plant. Exhaust gas out of EP was led and concentrated on Tenax GC for 10 minutes, and then heated at 270℃ to inject into a capillary column. Many compounds were separated, such as chlorobenzenes （mono～hexa）, chlorophenols（di～tetra） and aromatic hydro carbons, and then 21compounds were quantified. This analytical cycle was an hour. By operating this system continuously many data were obtained.
