Abstract: A method of benzene series rapid detection has been developed using gas chromatography with
surface acoustic wave detector (GC-SAW). Benzene series was tested by headspace under this condition. The
SAW detector temperature was set at 25 C. The initial temperature of DB-5 capillary column was 40 C, and
◦
◦
was temperature-programmed to 180 C with the rate of 10 C/s. The results show that the retention times of
◦
◦
chlorobenzene, m-xylene, styrene and cumene were 1.72 s, 1.86 s, 2.00 s, 2.22 s respectively, the detection limits
were 1.34 µg/L, 0.55 µg/L, 0.50 µg/L, 0.39 µg/L respectively, and the relative standard deviations were in
4.08%–5.98%. The recoveries were 82.7%–103.8%, and the linearities were good, linear correlation coefficients
were 0.9946–0.9993. Therefore, this method is suitable for benzene series rapidly emergency monitoring in
water.
