Agilent G3431-60531 – Electronic Pressure Control (EPC) Module | Agilent GC Platform
Engineering Background
The Agilent G3431-60531 is an OEM Electronic Pressure Control (EPC) module engineered for Agilent gas chromatography (GC) systems. EPC technology replaced traditional mechanical pressure regulators in Agilent GC platforms, delivering software-controlled, reproducible carrier gas and detector gas pressure management. This module is a critical pneumatic control component used across the Agilent 6890, 7890, and compatible GC series.
Product Positioning
Designed for laboratory instrument engineers and GC system integrators who require a verified OEM replacement or spare EPC module. The G3431-60531 ensures pressure accuracy, long-term repeatability, and seamless integration with Agilent ChemStation and OpenLAB CDS software environments. Konmask.com supplies this module with full traceability and pre-shipment verification.

Engineering Advantages
- Precision Pressure Regulation: Eliminates manual regulator drift; software-set pressure is maintained within tight tolerances across run sequences.
- Reproducibility: EPC modules enable method-to-method and instrument-to-instrument pressure reproducibility critical for regulated laboratory environments.
- Multi-Channel Architecture: Supports independent pressure control for inlet, detector, and auxiliary gas channels within a single GC chassis.
- Direct OEM Replacement: Drop-in compatibility with existing Agilent GC pneumatic manifold — no hardware modification required.
- Software Integration: Full compatibility with Agilent ChemStation, OpenLAB CDS, and EZChrom for automated pressure programming and diagnostics.
System Architecture & Signal Flow
The G3431-60531 EPC module interfaces directly with the GC’s internal pneumatic manifold and communicates with the GC main board via the instrument backplane. Pressure setpoints are transmitted from the GC controller (ChemStation/OpenLAB) → GC main board → EPC module → proportional solenoid valve → gas outlet to inlet/detector. A pressure transducer within the module provides closed-loop feedback, continuously correcting output to match the programmed setpoint. This architecture supports pressure programming ramps, constant flow mode, and pulsed pressure injection techniques.

Technical FAQ
Q: Is the G3431-60531 compatible with the Agilent 7890B GC?
A: Yes, the G3431-60531 is compatible with the 7890A and 7890B series. Please confirm your GC’s pneumatic configuration (number of EPC channels) before ordering.
Q: Can this module be used for both carrier gas and detector gas control?
A: EPC modules are channel-specific. The G3431-60531 controls a designated gas channel. Consult your GC’s pneumatic diagram to confirm the correct module for each channel.
Q: Do you supply refurbished units?
A: Yes. Refurbished units are available at reduced cost and carry the same 90-day functional warranty. Specify your preference at inquiry.
Q: What is the lead time for out-of-stock units?
A: Typical lead time for sourced units is 7–15 business days. Expedited sourcing is available — contact us for urgent requirements.
Q: Can I return the module if it is incompatible?
A: Yes. Konmask offers a 7-day compatibility return policy for uninstalled modules in original packaging. Contact support@konmask.com to initiate.
