The 14214 is a dual-stage electron multiplier for use in early model Thermo Electron ICP-MS instruments. The 14214 multiplier incorporates "ACTIVE FILM" materials in a discrete-dynode multiplier design to achieve exceptionally sensitive ion detection with long operating life and excellent air stability.
