Thermo Fisher U3000 Used High-Performance Liquid Chromatograph

Overview

The Thermo Fisher U3000 is a high-performance liquid chromatography (HPLC) system engineered for robustness, precision, and long-term operational stability in regulated and research laboratory environments. Built on Thermo Fisher Scientific’s proven UltiMate platform, the U3000 integrates dual-gradient capability, low-dispersion flow paths, and advanced solvent delivery architecture to support isocratic, gradient, and multi-step elution methods. Its core measurement principle relies on differential partitioning of analytes between a mobile phase (liquid solvent) and a stationary phase (packed column), with detection typically performed via UV-Vis absorbance (using a variable-wavelength or diode-array detector) or coupled mass spectrometry. This refurbished unit has undergone full functional validation—including pump linearity, gradient accuracy, injection repeatability, baseline noise, and dwell volume verification—per ASTM E2654-21 and ISO 17025-aligned protocols. All critical modules—including the quaternary pump (P/N 074321), autosampler (P/N 074322), column compartment (P/N 074323), and UV detector (P/N 074324)—have been inspected, cleaned, calibrated, and certified for performance consistency.

Key Features

• Quaternary high-pressure gradient pump delivering flow rates from 0.001 to 10.0 mL/min with ≤0.1% RSD flow precision and ≤0.2% gradient composition accuracy across 0–100% B.
• Low-volume, temperature-controlled autosampler with 100-position vial capacity, 0.1 µL minimum injection volume, and <1% RSD injection precision at 10 µL.
• Column oven supporting temperature control from 5 °C to 80 °C (±0.15 °C stability) to ensure retention time reproducibility.
• Variable-wavelength UV-Vis detector (200–800 nm range) with 10 mm pathlength flow cell, <±0.5 nm wavelength accuracy, and <0.5×10⁻⁵ AU/h baseline drift.
• Fully compatible with Thermo Chromeleon 7.2.10 CDS software for method development, sequence management, and 21 CFR Part 11-compliant audit trail generation.
• Refurbishment includes replacement of all high-wear components: pump seals, check valves, injector rotor seals, and detector lamp; plus full leak testing and pressure decay validation.

Sample Compatibility & Compliance

The U3000 accommodates standard 3.0–4.6 mm ID analytical columns (up to 250 mm length) and supports reversed-phase, normal-phase, ion-exchange, and size-exclusion chromatography applications. It meets essential compliance requirements for GLP and GMP environments when operated with validated methods and proper documentation. The system supports electronic signatures, user access levels, and secure data archiving per FDA 21 CFR Part 11 and EU Annex 11 guidelines. All refurbished units are supplied with a Certificate of Conformance (CoC), calibration report traceable to NIST standards, and IQ/OQ documentation templates aligned with ISO/IEC 17025:2017 and USP Analytical Instrument Qualification.

Software & Data Management

Chromeleon Chromatography Data System (CDS) version 7.2.10 serves as the native control and analysis platform. It enables real-time instrument monitoring, peak integration using multiple algorithms (e.g., valley-to-valley, tangent skim), custom reporting, and export to LIMS-compatible formats (e.g., .cdf, .csv, .pdf). Audit trails record all user actions—including method edits, sequence changes, and result reprocessing—with timestamps, operator IDs, and reason-for-change fields. Data integrity safeguards include encrypted database storage, automatic backup scheduling, and role-based permissions (Administrator, Analyst, Reviewer). Optional integration with Thermo Fisher’s SampleManager LIMS is available upon request.

Applications

This U3000 system is routinely deployed in pharmaceutical QC labs for assay and impurity profiling per ICH Q2(R2); environmental labs for EPA Method 8081B/8330B pesticide analysis; food safety labs for mycotoxin quantification (AOAC 2005.02); and academic research for natural product isolation and metabolite profiling. Its modular design allows seamless coupling to MS detectors (e.g., Thermo TSQ Altis) for LC-MS workflows, and compatibility with post-column derivatization modules expands utility for amino acid and carbohydrate analysis.

FAQ

What is the refurbishment scope for this U3000 system?

All fluidic path components—including pump heads, seals, check valves, injector stators/rotors, and detector flow cells—are replaced with genuine Thermo Fisher parts. The system undergoes full functional testing per manufacturer specifications and receives a 12-month limited warranty covering parts and labor.
Is Chromeleon software included and licensed?

Yes—each unit ships with a perpetual, single-seat Chromeleon 7.2.10 license pre-installed and activated. Software updates within the same major version are provided free of charge for the duration of warranty.
Can this system be qualified for GMP use?

Yes. We provide IQ/OQ protocol templates, test scripts, and raw data worksheets. Full PQ support and on-site qualification assistance are available as optional services.
What consumables and accessories are recommended for startup?

We recommend initial stocking of C18 columns (e.g., Acclaim 120, 4.6 × 150 mm), guard cartridges, HPLC-grade solvents, 2-mL amber vials with crimp caps, and pump seal kits (P/N 074321-001). A complete startup kit can be quoted separately.
Do you offer extended service contracts beyond the 1-year warranty?

Yes. Multi-year Platinum Support Plans are available, including priority remote diagnostics, annual preventive maintenance visits, and guaranteed 48-hour response for critical hardware failures.
