Thermo Scientific Accela U-HPLC System (Refurbished)

Overview

The Thermo Scientific Accela U-HPLC System is a high-performance, refurbished liquid chromatography platform engineered for method transfer, method development, and routine QC/QA applications requiring both conventional HPLC robustness and ultra-high-pressure capability. Based on the proven Accela architecture originally developed by Thermo Fisher Scientific in Canada, this system operates across a dual-pressure regime—supporting standard 6000 psi methods while delivering full functionality up to 15,000 psi for sub-2 µm particle column utilization. Its design integrates low-dispersion fluidics, minimized dwell volume (65 µL), and precise temperature control across all critical modules—pump, autosampler, column compartment, and detector—to ensure retention time stability, peak shape fidelity, and inter-laboratory reproducibility. As a legacy-compatible U-HPLC platform, it maintains full hardware and software interoperability with Thermo’s broader ecosystem of mass spectrometers (e.g., LTQ XL, TSQ Quantum Access, MSQ PLUS, LTQ Orbitrap) and Chromatography Data Systems (Chromeleon CDS v7.x), enabling seamless LC-MS workflows under regulated environments.

Key Features

• Two-mode pressure architecture: Fully functional at both 6000 psi (standard HPLC) and 15,000 psi (U-HPLC) without hardware modification
• Accela Quaternary Pump with 65 µL dwell volume—enabling rapid gradient equilibration and improved resolution for complex multi-component separations
• Accela PDA Detector featuring LightPipe™ optical path technology—delivering 5× higher sensitivity versus conventional diode array detectors through enhanced light throughput and reduced path-length dispersion
• Total Temperature Management (TTM) system—actively controlling temperature at the autosampler tray, column oven, and detector flow cell to ±0.2 °C, minimizing thermal-induced retention drift
• Surveyor Autosampler Plus with needle-in-loop injection and low carryover (<0.005%)—validated for precision injection volumes from 0.1 µL to 100 µL
• Pre-configured for Hypersil GOLD™ sub-2 µm column chemistries—optimized for high-efficiency separations with narrow peak widths and improved signal-to-noise ratios

Sample Compatibility & Compliance

The Accela U-HPLC accommodates a broad range of sample matrices—including pharmaceutical actives, biologics digests, environmental extracts, food contaminants, and polymer additives—when paired with appropriate column chemistries (C18, phenyl-hexyl, HILIC, ion-exchange). It supports fully validated operation per ICH Q2(R2), USP , and ASTM D4790 methodologies. All refurbished units undergo full functional verification against Thermo’s original factory specifications, including pressure integrity testing, gradient accuracy validation (±0.2% RSD), and baseline noise assessment (<±0.5 mAU). The system meets essential requirements for GLP and GMP environments when deployed with Chromeleon CDS v7.x configured for 21 CFR Part 11 compliance (audit trail, electronic signatures, user access controls).

Software & Data Management

Controlled exclusively via Thermo Scientific Chromeleon Chromatography Data System (CDS) v7.x, the Accela platform supports method building, sequence execution, real-time monitoring, peak integration, and report generation in accordance with ALCOA+ data integrity principles. Chromeleon provides built-in tools for system suitability testing (SST), calibration curve fitting (linear/nonlinear), and customizable reporting templates compliant with regulatory submission formats (e.g., FDA eCTD, EMA CTD). Audit trails are immutable, timestamped, and exportable in PDF/A or XML. Remote monitoring and secure web-based access are enabled via Chromeleon Web Services, facilitating multi-site deployment and centralized instrument management.

Applications

• Pharmaceutical QC release testing of APIs and finished dosage forms per USP monographs
• Stability-indicating assays for forced degradation studies (oxidative, hydrolytic, thermal)
• Impurity profiling and identification using LC-PDA-MS coupling
• Peptide mapping and intact protein analysis with sub-2 µm BEH C4 columns
• Environmental analysis of PFAS, pesticides, and PAHs per EPA Method 8330B and 8082A
• Food safety screening for mycotoxins, veterinary drug residues, and adulterants

FAQ

Is this unit covered by original Thermo Fisher warranty?

No—this is a professionally refurbished system backed by a 6-month limited hardware warranty administered directly by the refurbisher.
Can this Accela system be upgraded to support newer Chromeleon versions?

Yes—Chromeleon CDS v7.3.x is the latest supported version; upgrades require validated patch installation and may necessitate minor hardware firmware updates.
Does the system include validation documentation?

A complete Factory Acceptance Test (FAT) report is provided, including pressure test logs, gradient accuracy results, detector linearity data, and SST pass/fail records.
Are consumables and spare parts still available?

All major components—including pump seals, injector rotors, PDA flow cells, and column ovens—remain in active production or are available through Thermo’s legacy parts program.
What is the typical lead time for shipment?

Units are bench-tested and ready for immediate dispatch; standard lead time is 3–5 business days following order confirmation and payment clearance.
