Waters ACQUITY UPLC System

Overview

The Waters ACQUITY UPLC® System is a fully integrated, high-pressure liquid chromatography platform engineered for precision, speed, and robustness in regulated and research-intensive environments. Based on ultra-high performance liquid chromatography (UPLC®) technology — a proprietary Waters methodology grounded in the principles of van Deemter optimization and kinetic performance theory — the system operates at pressures up to 15,000 psi (1,034 bar), enabling the use of sub-2 µm particle-packed columns with minimal band broadening. This architecture delivers significantly enhanced resolution, sensitivity, and peak capacity compared to conventional HPLC systems employing 5 µm particles. The ACQUITY UPLC is not merely a faster HPLC; it redefines separation science by exploiting the full theoretical potential of small-particle chromatography while maintaining method transferability, system stability, and long-term reproducibility across thousands of injections.

Key Features

• High-pressure binary solvent manager capable of precise gradient delivery at flow rates from 0.01 to 2.0 mL/min with ≤0.1% RSD precision
• ACQUITY Sample Manager with low-dead-volume injection valve, temperature-controlled sample compartment (4–40 °C), and <100 nL carryover
• Column Manager with active pre-heating and cooling (5–90 °C), pressure-tolerant column switching, and real-time backpressure monitoring
• Integrated UPLC-optimized optics: TUV (Tunable UV/Vis), PDA (Photodiode Array), FLR (Fluorescence), and ELS (Evaporative Light Scattering) detectors — all calibrated to UPLC dwell volume and dispersion constraints
• Native compatibility with Waters mass spectrometers (Xevo®, Vion®, SYNAPT® series) and third-party MS platforms including Thermo Fisher Scientific (Orbitrap™, Q Exactive™), Sciex (TripleTOF®, QTRAP®), and Bruker (timsTOF®, maXis)
• ACQUITY UPLC Calculator software module for systematic, empirically validated HPLC-to-UPLC method translation — preserving selectivity while scaling column dimensions, flow rates, and gradient times
• Connections INSIGHT remote diagnostics and predictive maintenance capability, supporting GLP/GMP-aligned instrument uptime tracking and service event logging

Sample Compatibility & Compliance

The ACQUITY UPLC accommodates a wide range of sample matrices — including biological fluids (plasma, serum, urine), food extracts, environmental water samples, pharmaceutical formulations, and synthetic intermediates — without compromising chromatographic integrity. Its fluidic design minimizes extra-column dispersion and ensures compatibility with highly viscous or particulate-laden samples when used with appropriate filtration and guard column strategies. The system meets key regulatory expectations for analytical instrumentation: hardware and firmware are compliant with FDA 21 CFR Part 11 requirements when deployed with Empower™ 3 Software (GxP edition); supports audit trail, electronic signatures, and role-based access control. It is routinely validated per ICH Q2(R2), USP , and ISO/IEC 17025 guidelines in QC laboratories performing identity, assay, impurity profiling, and stability-indicating analyses.

Software & Data Management

Data acquisition, processing, and reporting are managed through Waters Empower™ Chromatography Data Software (CDS), available in both Professional and GxP-compliant editions. Empower provides full support for UPLC-specific parameters — including dwell volume compensation, pressure-dependent retention modeling, and peak deconvolution algorithms optimized for narrow, tall UPLC peaks. All raw data files (.raw) are stored in an open, non-proprietary format compatible with third-party chemometric tools (e.g., SIMCA, MATLAB, Python-based LC-MS libraries). System suitability testing (SST), calibration curve evaluation, and report generation follow configurable templates aligned with internal SOPs and external standards such as ASTM D7594 (petroleum analysis) or AOAC Official Methods (food safety).

Applications

The ACQUITY UPLC serves as a foundational platform across multiple analytical domains: pharmacokinetic and ADME studies requiring rapid, high-sensitivity quantitation of drug metabolites; targeted and untargeted metabolomics workflows leveraging its superior peak capacity for complex biological extracts; residual solvent analysis in APIs per ICH Q3C; peptide mapping and intact protein characterization in biopharma development; pesticide multiresidue screening in fruits and vegetables (EU MRL compliance); and routine quality control of small-molecule pharmaceuticals under cGMP conditions. Its modularity allows seamless integration into automated lab environments via LIMS interfaces and robotic sample handling systems.

FAQ

Is this unit refurbished and certified to original Waters specifications?
Yes — all ACQUITY UPLC systems offered are factory-refurbished by Waters-authorized service centers, including full mechanical recalibration, detector validation, pump linearity verification, and system suitability testing using NIST-traceable standards.
What documentation accompanies the instrument?
Each unit ships with a Certificate of Conformance, detailed refurbishment report, calibration records, and a complete set of operational manuals in English. IQ/OQ documentation packages are available upon request.
Can this system be upgraded to include mass spectrometry detection?
Yes — the ACQUITY UPLC features standardized MS interface ports (e.g., ESI, APCI sources) and is pre-configured for direct coupling to Waters and third-party mass spectrometers. Required interface hardware and software licenses must be procured separately.
Does the 6-month warranty cover labor and parts globally?
The warranty covers hardware defects and labor for repair at authorized Waters service locations in North America, Europe, and APAC regions. Extended service plans with global coverage are available for purchase prior to shipment.
