WebIt is obvious that direct analysis of pentachlorophenol by LC-MS/MS without derivatization would yield low sensitivity. So, selective ion monitoring (SIM) at 263, 265, 267 experiments were conducted for the analysis of pentachlorophenol, and the detection parameters were optimized to make the base peak of 263, 265, 267 have a good signal value.
