给大家看看碰撞池是怎么消除干扰的

ORS can be operated without using highly reactive gases. Octopole design allows higher cell pressures increasing reaction cross section due to better ion beam focussing
He Mode
Collisionally Induced Dissociation – the interference is broken apart when it impacts the He atom
Energy Discrimination – the larger polyatomic species (greater ionic radii) loose more energy than the smaller analyte species and cannot enter the QP – effectively a molecular filter
Aided by the Agilent ShieldTorch System – all ions enter the Octopole with well-defined narrow energy distribution
H2 Mode
Charge Transfer – electron transferred from (or to) hydrogen, producing a neutral species

Actually both modes use Energy Discrimination, at least in part
