Description

Agilent G2855-61500 Dean’s Switch with EPC & Solenoid Valve Overview

The Agilent G2855-61500 is an inert Dean’s Switch manifold assembly used for heart-cutting and column-switching applications on any gas chromatography system, paired here with an Electronic Pneumatics Control (EPC) module and Solenoid Valve for a complete, ready-to-install switching setup. Agilent has discontinued this part number, making a tested, working unit increasingly difficult to source new — this refurbished assembly has been fully tested and verified in working condition by Alliant Scientific.

The Dean’s Switch allows a portion of the GC effluent stream to be diverted to a second column or detector without interrupting the primary analysis, commonly used to isolate interfering compounds, route specific fractions for secondary analysis, or extend column life by diverting unwanted matrix components away from the analytical column. The inert manifold design minimizes analyte adsorption and carryover, preserving sensitivity for trace-level and reactive compound analysis.

This Agilent G2855-61500 Dean’s Switch with EPC & Solenoid Valve is offered fully tested and verified in working condition by Alliant Scientific.

Includes:

  • Agilent G2855-61500 Dean’s Switch (Inert Manifold Assembly)
  • Electronic Pneumatics Control (EPC) Module
  • Solenoid Valve
  • 30-Day Warranty

FAQ (Frequently Asked Questions)

What is a Dean’s Switch used for?

A Dean’s Switch diverts a portion of the GC effluent stream to a second column or detector without interrupting the primary analysis — commonly used for heart-cutting, isolating interfering compounds, or protecting the analytical column from unwanted matrix components.

Is this part still available new from Agilent?

No — Agilent has discontinued this part number. This refurbished, tested unit is a way to source a working replacement for GC systems that still rely on this configuration.

What’s included with this Dean’s Switch?

The G2855-61500 Dean’s Switch manifold assembly, an Electronic Pneumatics Control (EPC) module, and a Solenoid Valve.

Is this compatible with my GC system?

Agilent designed this Dean’s Switch to be compatible with any gas chromatography system, not limited to a specific GC model.

Does this unit include a warranty?

Yes — this unit has been tested and verified working, and ships with a 30-day warranty.
