Thermo Finnigan Low Pass Filter for LCQ Duo

The Thermo Finnigan 97000-61380 Low Pass Filter for LCQ Duo MS system is a complete electronic filter assembly used within the LCQ Duo liquid chromatography/mass spectrometry (LC/MS) instrument platform. This unit integrates the main PCB, a set of four air-wound inductors, and a metal mounting bracket/housing enclosure, serving as a dedicated signal conditioning and filtering component within the instrument’s electronic subsystem.

This assembly is responsible for low-pass filtering functions within the LCQ Duo system electronics, helping maintain signal integrity and stable operation of downstream analytical modules. It is designed as an integrated service replacement module for internal instrument repair or refurbishment.
