The Thermo Scientific Dionex ICS-5000 DP Dual Pump Module is a high-pressure dual-piston pump module designed as a core component of the Dionex ICS-5000 ion chromatography platform. The unit shown in the image is identifiable as a Dionex ICS-5000 DP and is part of the modular ion chromatography system used for analytical and capillary IC applications.

The ICS-5000 DP contains two independent pump channels and can be configured for different combinations of capillary and analytical pumping. Thermo Scientific documentation describes the DP as using dual-piston, microprocessor-controlled, constant-stroke, variable-speed pumps with chemically inert PEEK pump heads and flow paths.

Depending on configuration, the two pumps can be used for dual-channel chromatography, auxiliary pumping or independent pumping. Analytical configurations can support isocratic or low-pressure proportioned-gradient operation, while capillary configurations are designed for high-pressure ion chromatography.

Applications

The Dionex ICS-5000 DP is used in ion chromatography (IC) workflows for separation and analysis of inorganic ions, organic acids, carbohydrates and other ionic compounds. It can form part of complete Dionex ICS-5000 systems incorporating an eluent generator, detector/chromatography module, suppressor and autosampler.

The DP has been used in published analytical applications for measurements including inorganic anions, carbohydrates and cations. Thermo Scientific application documentation also shows ICS-5000 systems configured with DP pumps for environmental and high-pressure capillary ion chromatography applications.

Technical Specifications

Thermo Scientific specifications list an analytical flow range of 0–10.000 mL/min and capillary flow range of 0.001–3.000 mL/min. Maximum documented operating pressures are 5000 psi for analytical configurations and 6000 psi for capillary configurations, although older capillary pump versions may have lower pressure ratings and should be verified before operation.

The DP can contain different combinations of pump types. Thermo Scientific documentation describes configurations including two isocratic capillary pumps, two analytical pumps, or one capillary and one analytical pump. The exact configuration of the photographed unit should therefore be confirmed from its internal pump heads and model/nameplate information.

Benefits of Refurbished Laboratory Equipment

A refurbished Dionex ICS-5000 DP Dual Pump Module can provide laboratories with access to established high-pressure ion chromatography pumping technology for existing Dionex modular IC systems. Its dual-pump architecture allows laboratories to configure separate flow paths for chromatography, auxiliary delivery or other compatible IC functions.

Refurbished IC equipment can be useful for analytical laboratories, environmental testing facilities, pharmaceutical research, food and beverage testing, academic laboratories and research facilities. Before use, the pump should be professionally inspected for piston-seal condition, check valves, pressure stability, flow accuracy, degassing performance and leakage.

Additional Information

The photographed unit is a used/refurbished Thermo Scientific Dionex ICS-5000 DP Dual Pump Module and shows visible cosmetic wear, dirt and discoloration. The photograph does not confirm the internal pump configuration, pump-head type, degasser configuration, tubing, fittings or software/interface accessories.

The ICS-5000 DP is a module rather than a complete ion chromatograph and requires compatible Dionex system components such as a detector/chromatography module, injection system and appropriate IC plumbing for a complete analytical setup. Thermo Scientific documentation describes the ICS-5000 as a modular platform that can be configured for analytical and capillary IC applications.
