Thermo Finnigan Power Supply Module for LCQ Duo

Thermo Finnigan 97000-98041 Electron Multiplier High Voltage Power Supply (8 kV)

The Thermo Finnigan 97000-98041 is a high-precision, regulated high-voltage power supply module engineered for the LCQ Duo, LCQ Deca, and TSQ mass spectrometry platforms. This module provides the stable 8 kV (100 µA) output necessary to bias the electron multiplier, ensuring the efficient amplification of secondary electrons generated during the detection process. Designed for extreme stability and low ripple, the 97000-98041 is critical for maintaining the high signal-to-noise ratio and wide dynamic range required for sensitive LC/MS/MS analytical sequences.

Technical Performance and Design

• Regulated 8 kV Output: Delivers a consistent high-voltage bias (up to 8,000V @ 100 µA) to the electron multiplier, enabling the high-gain amplification required for trace-level analyte detection.

• Low-Noise Circuitry: Engineered to provide ultra-clean voltage output, minimizing electronic noise and interference that could otherwise compromise the integrity of the mass spectral baseline.

• Continuous Analytical Workload: Built with high-grade industrial components designed to maintain steady output during long-duration runs and high-throughput automated laboratory workflows.

• Modular Installation: Features secure, high-voltage internal connections and a compact form factor designed for direct integration into the LCQ Duo's high-voltage electronics bay.
