Electron Multipliers for the Amplification and Detection of Charged Particles in Quadrupole Mass Spectrometers (QMS)

Hamamatsu’s electron multipliers have a broad dynamic range, sturdy structure, and are more economical than MCP assemblies.

Key Features

R8811 Electron Multiplier

  • Compact size
  • Detects only positive ions
  • Bake-out temperature 350°C
  • Off-axis structure reduces effects from noise produced by the ionization process (e.g., X-rays and UV)
  • Has electron multiplier as well as Faraday cup components, enabling the detection of ions from large amounts to trace quantities

R4146-10 Electron Multiplier

  • Thin format
  • Detects positive ions only
  • Bake-out temperature 350°C

R6985-80 Electron Multiplier

  • Detects negative and positive ions
  • Can determine very heavy ions (e.g., large proteins)
  • Off-axis structure reduces effects from noise produced by the ionization process (e.g., x-rays and UV)
