Agilent ERC-6210 | 24 V DC Diaphragm Vacuum Pump

Description

Core Product Summary (Brand / Model / Key Attributes)

The Agilent ERC-6210 is a 24 V DC diaphragm vacuum pump used as the vacuum-generation component in Agilent HPLC solvent degassing assemblies. It is identified with Agilent vacuum-pump part number G1322-60000 and is associated with the Agilent 1100, 1200, and 1260 LC degasser product families.

The pump is used in the Agilent G1322A Standard Degasser and G1379B Micro Vacuum Degasser. Its nameplate identifies a 24 V DC, 210 mA supply requirement and a maximum vacuum of 6.0 kPa. In the G1379B micro degasser, the pump evacuates the four-channel vacuum chamber containing microstructured membranes, allowing dissolved gases to be removed from the mobile phase before it reaches the LC pump.

Key Technical Specifications

Detailed Product Overview

The Agilent ERC-6210 is the vacuum pump identified by Agilent part number G1322-60000 for use in Agilent LC degasser assemblies. Its function is to create the low-pressure environment required for membrane degassing: dissolved gases diffuse through the degasser membranes and are removed by the vacuum side of the system.

In the G1379B Micro Vacuum Degasser, the pump is installed inside the degasser enclosure and is connected through tubing to the solenoid-valve assembly. Its electrical cable connects to connector CN2 on the degasser control assembly. The pump is retained by fixing plates and sits on rubber feet, with the inlet tube connected before the pump is secured in place.

The ERC-6210 is relevant when a G1322A or G1379B degasser fails to develop sufficient vacuum or exhibits an electrically defective pump. Agilent’s G1379B service documentation identifies G1322-60000 as the required vacuum-pump part for pump replacement in that unit. The same part number is also listed by Agilent for the G1322A Standard Degasser environment.

Because this is an internal LC degasser component rather than a standalone laboratory instrument, selection should begin with the degasser model and the marking on the installed pump. The ERC-6210 marking, Agilent part number G1322-60000, and the connected degasser model should all be checked before ordering or installing a replacement.

Engineering Selection Highlights

• ERC-6210 corresponds to Agilent vacuum-pump part G1322-60000, so both identifiers should be matched during spare-part selection.
• It is used in the Agilent G1322A Standard Degasser, making it applicable to 1100/1200/1260 LC configurations that employ that degasser.
• It is also the documented replacement pump for the G1379B Micro Vacuum Degasser, where it evacuates the four-channel membrane vacuum chamber.
• The 24 V DC, 210 mA electrical rating must match the degasser control assembly, which supplies the pump through connector CN2.
• The 6.0 kPa maximum-vacuum marking provides a benchmark for diagnosing inadequate degasser vacuum, although actual system vacuum depends on the complete pump, tubing, valve, chamber, and seal condition.
• The pump is mechanically retained by fixing plates and connected to the solenoid assembly by tubing, so replacement requires both electrical disconnection and vacuum-path reconnection.

System Compatibility & Integration Requirements

Dimensions, Mounting & Connection Notes

• The pump is mounted inside the degasser on rubber feet, secured by fixing plates and two holding screws.
• The vacuum inlet connects to tubing from the solenoid-valve assembly.
• The pump cable connects to connector CN2 on the degasser control assembly.
• The nameplate specifies 24 V DC at 210 mA.
• The maximum vacuum marking is 6.0 kPa.
• Replacement requires removal of the degasser top cover, disconnection of the pump cable and inlet tube, removal of the fixing plates, and refitting in reverse order.

FAQ

What is the Agilent ERC-6210?
It is a 24 V DC diaphragm vacuum pump used inside Agilent HPLC solvent degassers to generate the vacuum required for membrane degassing.

What Agilent part number corresponds to ERC-6210?
The associated Agilent vacuum-pump part number is G1322-60000.

Which Agilent degassers use the ERC-6210?
It is associated with the Agilent G1322A Standard Degasser and is the documented vacuum pump for the G1379B Micro Vacuum Degasser.

What electrical supply does the ERC-6210 require?
It requires 24 V DC at 210 mA and connects to the degasser control assembly at connector CN2.

What vacuum level is marked on the ERC-6210?
The pump nameplate identifies a maximum vacuum of 6.0 kPa.

When should the ERC-6210 be replaced?
Agilent service documentation identifies pump replacement when the micro degasser is not generating sufficient vacuum or when the pump is electrically defective.

Is ERC-6210 a standalone vacuum pump?
No. It is an internal degasser component intended for installation within a compatible Agilent degasser assembly.

Verification & Troubleshooting Notes

• Confirm the installed pump marking—ERC-6210 and G1322-60000—before ordering a replacement.
• If the degasser does not reach expected vacuum, inspect the complete vacuum path: pump, tubing, solenoid valve, vacuum chamber, membranes, fittings, and seals. Low vacuum can result from any of these, not only the pump.
• Verify that the pump cable is firmly connected to CN2 and that the 24 V DC supply path is intact.
• During pump replacement, avoid reversing the vacuum-tubing connection or trapping the cable beneath the fixing plates.
• Do not operate the degasser with an open or disconnected vacuum path; restore the tubing and enclosure before applying power.
• Follow Agilent’s degasser service procedure and site laboratory safety practices when working inside the instrument.
