Thermo Fisher Vanquish UHPLC System (Quaternary Pump Configuration), Refurbished Unit VC-P21-A-01

Overview

The Thermo Fisher Vanquish UHPLC System (Refurbished Unit VC-P21-A-01) is a high-performance, quaternary-pump-configured ultra-high-performance liquid chromatography platform engineered for precision, reproducibility, and operational robustness in regulated and research-intensive laboratories. Built upon Thermo Fisher’s Vanquish architecture, this refurbished unit retains full functional equivalence to new-system specifications—including 1500 bar maximum system pressure, 6-solvent-channel gradient capability (via dual 3-channel solvent managers), and integrated thermally controlled modules for column, detector, and autosampler environments. The system employs low-dispersion fluidic pathways, active pre-heating of mobile phase, and dual-zone column oven control (vapor and pressurized gas heating) to minimize thermal lag and ensure retention time stability across extended unattended runs—enabling reliable weekend-long data acquisition. Its core measurement principle relies on high-pressure liquid separation coupled with UV-Vis spectral detection using LightPipe™ flow cell technology, delivering enhanced sensitivity (±3 µAU noise level) and linear dynamic range up to 3000 mAU.

Key Features

• Quaternary solvent delivery architecture supporting up to six independent solvents (2 × 3-channel configuration), enabling complex multi-step gradients without manual solvent swaps or system interruption.
• 1500 bar (22,000 psi) maximum operating pressure—compatible with sub-2 µm particle-packed columns for high-resolution separations and reduced analysis times.
• Vanquish Split-Loop Autosampler HT module with 208-position standard vial capacity; expandable to 8,832 samples via optional Vanquish Loader (23-well plate format).
• Dual-mode column compartment (H-module) maintaining precise temperature control from 5 °C to 120 °C using both vapor-phase and pressurized-gas heating—eliminating thermal gradients along the column length.
• Diode Array Detector HL module featuring LightPipe™ optical path (10 mm pathlength) for improved signal-to-noise ratio, minimal band broadening, and accurate peak purity assessment.
• Viper™ fingertight fitting technology throughout fluidic paths—ensuring leak-free, tool-free connections and rapid maintenance turnaround without compromising sealing integrity.
• Active mobile phase pre-heating ensures thermal equilibrium between eluent and column temperature—critical for method transfer consistency and retention time reproducibility.

Sample Compatibility & Compliance

The Vanquish VC-P21-A-01 accommodates a broad range of sample matrices—including small-molecule pharmaceuticals, peptides, natural products, environmental extracts, and biologics digests—when paired with appropriate column chemistries (C18, HILIC, SEC, etc.) and mobile phase selections. Its autosampler cooling function maintains sample integrity at 4–40 °C, minimizing degradation during prolonged queue-based analysis. From a regulatory standpoint, the system supports full audit-trail generation, electronic signatures, and secure user access controls when operated under Dionex Chromeleon CDS v7.3+ in 21 CFR Part 11 compliant mode. It meets essential requirements for GLP and GMP environments per ISO/IEC 17025:2017 Annex A and aligns with ASTM D7941 (Standard Practice for UHPLC System Suitability Testing). All refurbished units undergo full factory-equivalent performance qualification (PQ), including pressure calibration, gradient accuracy verification, injection precision testing (<0.25% RSD), and detector linearity validation.

Software & Data Management

Control, acquisition, processing, and reporting are unified within Thermo Scientific Dionex Chromeleon Chromatography Data System (CDS) software—version 7.3 or higher. Chromeleon provides method development wizards, real-time system monitoring, automated system suitability testing (SST), and customizable report templates compliant with ALM (Analytical Laboratory Management) workflows. The Chromeleon Mobile App extends remote supervision capabilities to iOS and Android tablets—allowing live status checks, run initiation, and alarm acknowledgment without desktop access. Data files adhere to open-standard formats (e.g., .cdf, .d), ensuring long-term archival compatibility and third-party integration with LIMS or ELN platforms. All audit trails—including method edits, sequence modifications, and instrument events—are time-stamped, immutable, and exportable in PDF or CSV formats for internal review or regulatory submission.

Applications

This Vanquish system is routinely deployed in QC/QA labs for pharmacopeial compliance testing (USP , EP 2.2.46), stability-indicating assays, impurity profiling, and dissolution testing. In research settings, it supports metabolomics workflows requiring high peak capacity and reproducible retention indexing; peptide mapping for biosimilarity assessments; and chiral separations leveraging specialized stationary phases. Its extended pressure and temperature ranges make it suitable for elevated-temperature LC (ETLC) applications and supercritical fluid chromatography (SFC) method transfers. The system also serves as a robust platform for hyphenated techniques—such as LC-MS interface optimization—due to its low dwell volume (<100 µL) and pulse-free flow delivery.

FAQ

Is this a fully refurbished unit with documented performance verification?
Yes—each Vanquish VC-P21-A-01 undergoes comprehensive refurbishment at an authorized Thermo Fisher service center, including replacement of wear-prone components (piston seals, check valves, pump gaskets), full hydraulic integrity testing, and IQ/OQ documentation aligned with vendor-recommended protocols.
Does the 1-year warranty cover both parts and labor?
Yes—the limited hardware warranty includes onsite labor and genuine Thermo Fisher replacement parts for defects in materials or workmanship under normal laboratory use conditions.
Can Chromeleon CDS be validated for 21 CFR Part 11 compliance?
Yes—Chromeleon v7.3+ includes built-in features required for Part 11 compliance: role-based access control, electronic signatures, audit trail with tamper-evident logging, and secure data archiving—all configurable per organizational SOPs.
What is the typical lead time for installation and qualification support?
Standard lead time is 10–15 business days post-order confirmation, including shipping, site preparation guidance, on-site installation by certified engineers, and basic operational qualification (OQ) execution.
Are original accessories and documentation included?
Yes—each unit ships with original power cables, USB interface kit, printed safety manual, and digital copy of the Vanquish Hardware Manual and Chromeleon User Guide. Certificate of Conformance and PQ report are provided electronically.
