Collision energy, collision gas and collision gas pressure effects on the formation of 2,3,7,8-tetrachlorodibenzo-p-dioxin and 2,3,7,8-tetrabromodibenzo-p-dioxin product ions

Abstract

The effects of collision energy, the nature of the collision gas, and collision gas pressure on formation of product ions of 2,3,7,8-tetrachlorinated dibenzo-p-dioxin (TCDD) and 2,3,7,8-tetrabrominated dibenzo-p-dioxin (TBDD) and approaches to determine optimum conditions for mass spectrometry/mass spectrometry (MS/MS) of TCDDs ant TBDDs were investigated. The results demonstrate the optimum collision energy conditions are dependent on the pressure of argon, nitrogen, and xenon and independent of helium pressure
