Electron Multipliers
Precision ion detection for your most demanding applications
From GC-MS and LC-MS to TOF and ICP-MS, IMI offers a broad portfolio of electron multipliers engineered for high sensitivity, long life, and minimal maintenance.
Whether you're developing next-generation analytical instruments or optimizing current platforms, our multipliers deliver the signal performance, system reliability, and integration flexibility your application demands.
With options including discrete dynode and channel multipliers - available in both ceramic and glass - we help leading instrument manufacturers improve detection performance, extend instrument uptime, and reduce calibration cycles.
Why Choose IMI for Electron Multipliers?
Proven Performance Across Modalities
Our multipliers are designed for seamless integration into a wide range of analyzer types:
- GC-MS & LC-MS: Shielded, encapsulated designs reduce maintenance and recalibration, improving ease of use and throughput.
- ICP-MS: Dual analog and pulse-counting sections deliver wide dynamic range (~10¹⁰) without the need for complex sample prep.
- TOF-MS: Ultra-fast pulse response (as low as 500 ps) ensures precise mass quantification and improved instrument uptime.
Application-Tuned Designs
Every multiplier is optimized for its environment—whether you're working with high-mass ions, compact analyzers, or portable systems:
- Ceramic Multipliers: Offer best-in-class linearity and lifetime, reducing calibration frequency and service intervals.
- Glass Multipliers: Economical and compact, ideal for analog signal detection and miniaturized or high-pressure applications.
- HED Integration: High Efficiency Dynodes improve detection of high-mass ions and ensure uniform sensitivity across the full m/z range.
- Versatile Mounting: Choose from manifold, flange, or barb connections, with options for positive and negative ion detection.
Built for Reliability
Our electron multipliers are engineered to minimize drift, baseline noise, and recalibration needs. Long-life materials, robust construction, and integration-ready form factors help you reduce downtime, streamline servicing, and maintain tight performance tolerances over time.
