Channel Electron Multiplier (CEM)
High Sensitivity & Superior Signals
Our partner is the original manufacturer of Channeltron® electron multipliers, which offer the highest dynamic range to assure an absolutely linear response beyond the limits of most analytical instruments.
The advanced designs provide the highest sensitivity through superior signal collection and noise reduction. Available in various shapes, sizes, and voltages, the Channeltron® electron multipliers are engineered to deliver the highest performance available on the market. Cones, grids, coatings, collectors and leads can all be specified, or you can choose one of our many standard models. Improvements in conversion dynode technology have resulted in structures capable of operation at higher voltages and materials with improved ion-to-electron conversion yields for better sensitivity at higher masses.
More than half of the world’s mass spectrometer manufacturers rely on these Channeltron® detectors to improve the reliability of their instruments. Due to their low mass and high gain, Channeltron® electron multipliers are also used in many nuclear physics labs and space applications to count electrons and charged particles in pulse mode operation. Other applications include residual gas analysis, plasma analysis, Auger, electron spectrometers, SEM, FIB and leak detectors.
How does a Channeltron® work?
Improvements in conversion dynode technology have resulted in structures capable of operation at higher voltages and materials with improved ion-to-electron conversion yields for better sensitivity at higher masses.
Channel electron multipliers directly detect and amplify energetic photons and charged particles such as positive and negative ions, electrons and assorted molecular and subatomic particles.
High pressure Electron Multiplier Detectors
In today’s evolving market, there is a greater need for smaller detectors that are able to perform in high pressure and poor vacuum environments. Learn more about the products our partner designs for these applications:

Optimizing the Performance
The performance of your mass spectrometer is often limited by the capabilities of the detector. Our partner has developed an electron multiplier family called the MAGNUM™, which provides significantly improved performance by increasing linear output current, reducing noise, and increasing detector life.
