pressure that is much higher than the vacuum required by the ion lens and mass spectrometer portions of the instrument. The interface allows the plasma and the ion lens system to coexist and the ions generated by the plasma to pass into the ion lens region. The interface consists of two or three inverted funnel-like devices called cones.

at a high negative voltage. The impact of the ion releases several free electrons from the dynode surface, which are repelled from the high negative voltage at the front and strike the next dynode. Each electron which strikes a dynode releases several electrons from that surface and hence the device is called "electron multiplier".
