Dionex UltiMate 3000 Used HPLC System

Overview

The Dionex UltiMate 3000 is a high-performance, modular liquid chromatography system engineered for precision, robustness, and long-term operational stability in regulated and research laboratory environments. As a legacy platform from Thermo Fisher Scientific (originally developed by Dionex), the UltiMate 3000 architecture implements low-pressure quaternary gradient mixing, dual-piston reciprocating pump technology, and real-time pressure monitoring to ensure exceptional flow accuracy and gradient reproducibility—critical for method transfer, QC/QA validation, and GLP-compliant workflows. This pre-owned system has undergone full functional verification including pump integrity testing, autosampler carryover assessment, detector baseline stability evaluation, and column oven thermal calibration. All core modules—including the LPG-3400SD pump, WPS-3000SL analytical autosampler, VWD-3100 variable-wavelength detector, and TCC-3000RS column compartment—are original Dionex components with documented service history and verified firmware compatibility (Chromeleon™ 7.2+).

Key Features

• Quaternary low-pressure gradient pumping with <0.05% RSD flow precision and ±0.1% flow accuracy across 0.001–10 mL/min range
• Integrated four-channel vacuum degasser with independent channel control (pH 1–14 compatible solvents)
• WPS-3000SL autosampler supporting 120 × 2.0 mL vials or configurable multi-format trays (including 96-well and 384-well microplates)
• Automated needle wash with programmable pre- and post-injection rinse cycles; cross-contamination <0.004%
• VWD-3100 dual-beam UV-Vis detector featuring deuterium/tungsten lamp source, 190–900 nm wavelength scanning, and <±2.5 µAU noise at 254 nm
• TCC-3000RS column oven with ±0.1 °C temperature stability, rapid heating/cooling (<15 min between 20–50 °C), and support for up to twelve 30 cm columns
• USB-native instrumentation interface enabling plug-and-play connectivity without proprietary interface cards
• Full compliance with Chromeleon™ 7.x software architecture, supporting 21 CFR Part 11 audit trails, electronic signatures, and secure user role management

Sample Compatibility & Compliance

The UltiMate 3000 accommodates standard reversed-phase, ion-exchange, size-exclusion, and hydrophilic interaction chromatography (HILIC) methods using common silica- or polymer-based stationary phases. Its solvent compatibility spans pH 1–14, accommodating aggressive mobile phases used in IC and preparative applications. The system meets foundational requirements for ISO/IEC 17025-accredited laboratories when operated within validated methods and maintained per manufacturer-recommended service intervals. All hardware modules are traceable to original Dionex part numbers and serial identifiers. Documentation includes factory calibration certificates (where available), recent performance qualification reports, and a full chain-of-custody record covering acquisition, refurbishment, and final verification.

Software & Data Management

Chromeleon™ Chromatography Data System (CDS) v7.2 or later serves as the native control and analysis platform. It provides full instrument control, sequence scheduling, real-time data acquisition at up to 100 Hz, peak integration with customizable baselines and retention time windows, and automated report generation compliant with internal SOPs. Audit trail functionality records all user actions—including method edits, sequence modifications, and result reprocessing—with timestamps, operator IDs, and reason codes. Data storage adheres to ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available) and supports export to CSV, PDF, and XML formats. Integration with enterprise databases (Oracle, Microsoft SQL Server, Jet Engine) enables centralized data warehousing and cross-platform analytics.

Applications

This system is routinely deployed in pharmaceutical stability-indicating assays, environmental anion/cation profiling (e.g., nitrate, sulfate, fluoride), food additive quantification (e.g., benzoates, sorbates), polymer molecular weight distribution analysis, and natural product fingerprinting. Its low dead volume design (<690 µL gradient delay) and high-pressure tolerance (62 MPa) make it suitable for UHPLC-compatible columns (sub-2 µm particles) when paired with appropriate frits and fittings. Method transfer from legacy Dionex or Thermo HPLC platforms is highly predictable due to consistent dwell volume, dwell time, and gradient dwell compensation algorithms embedded in Chromeleon™.

FAQ

Is this system fully refurbished and tested prior to shipment?
Yes. Each unit undergoes comprehensive functional testing—including pressure hold tests, gradient accuracy verification, autosampler precision assessment, detector linearity and noise evaluation, and thermal stability validation—per Thermo Fisher’s recommended PQ protocol.
What documentation accompanies the system?
You receive a Certificate of Operational Verification, firmware version log, Chromeleon™ license activation file, and a detailed service history summary. Original manuals and safety compliance statements are provided digitally.
Can this system be integrated into an existing Chromeleon™ network environment?
Yes. The USB-native architecture ensures seamless integration with Chromeleon™ 7.2+ installations on Windows 10/11 workstations. No additional interface hardware is required.
Does the 12-month warranty cover parts and labor globally?
The warranty covers all original Dionex components and labor for onsite or depot-based repair within North America, Europe, and select APAC territories. Extended coverage options are available upon request.
Are consumables and spare parts still available?
All major modules (pump seals, autosampler rotors, detector lamps, column oven heaters) remain in active production or are available through Thermo Fisher’s legacy parts program with typical lead times under 10 business days.
