Notes: Positive and negative ion.

Channeltron® Electron Multipliers offer the highest dynamic range to assure a linear response beyond the limit of most analytic instruments. Recent improvements in design have resulted in higher voltage operation, improved ion-to-electron conversion yields, and better sensitivity at higher masses.

Additionally, any of our Channeltron® Electron Multipliers can be ordered as complete assemblies to replace current detector assemblies in most mass spectrometers.

PHOTONIS manufactures Channeltron® Electron Multipliers in a wide range of shapes and sizes for many current and legacy mass spectrometers. Cones, grids, coatings, collectors and leads can all be specified, or you can choose one of our many standardized models. Our exclusive Extended Dynamic Range option can be added to any order, extending the dynamic range of your CEM, and enhancing its useful lifetime far beyond those of other manufacturers.


Positive and Negative Ion

base view

Four styles of multipliers are used on all models of Agilent (Hewlett Packard) mass spectrometers.

Model 4770 (PN 30092) is for positive ion use only while the Model 4770B (PN 30093) is for instruments with both positive and negative ion capabilities.


Photonis Electron Multipliers are designed and manufactured to the highest standards in the world. It is warranted against all defects in materials and workmanship for one year after installation. In addition, if you install your electron multiplier and are not completely satisfied with its performance, return it promptly for replacement or refund.
