The dynamic range of mass selected detector, which is very popular recently
because of the simplicity and cheap price, was determined by using priority polltitants. The All. _&.1 applied priority pollutants were four pesticides, 4,4´-DDE and 4,4´-DDD, which sho,.c the sharp peaks, and a-endosulfan and fl-endosulfan, which show the broad peaks in SIM
ite, cyani Chromatogram. The dynamic range of the 4,4´-DDE and the 4,4 -DDD was 0.1-3000
g / ml. The broad peaks of the a-endosulfan and 6endosulfan resulted in 0.25 - 3000pg / ml of ´471
dynamic range.
