Waters ACQUITY UPLC Sample Manager with Column Heater

Overview

The Waters ACQUITY UPLC Sample Manager with integrated column heater is a high-precision, second-hand liquid chromatography (LC) autosampler engineered for robust performance in regulated and research-intensive laboratories. Designed as a core module of the ACQUITY UPLC platform, it operates on the principle of low-dispersion, high-pressure sample introduction—enabling reproducible injection volumes from 0.1 µL to 100 µL with sub-microliter precision. Its integrated Peltier-based column heater maintains thermal stability across the analytical flow path, critical for retention time reproducibility and method transfer between UPLC systems. This refurbished unit has undergone full functional validation per Waters’ OEM specifications—including syringe wash efficiency, needle seal integrity, carryover assessment (<0.005%), and temperature uniformity mapping across the column compartment—and meets baseline operational criteria for GLP-compliant environments.

Key Features

• Programmable sample compartment temperature control from 4 °C to 40 °C, adjustable in precise 1 °C increments; validated stability ±0.5 °C at setpoint under continuous operation
• Flexible plate handling architecture supporting multiple microplate formats: up to 21 × 384-well plates (8,064 positions), or configurable combinations including 11 × intermediate-height plates, 7 × deep-well (2 mL vial) plates, or 1 × standard ANSI/SLAS microtiter plate
• Integrated column heater with active temperature monitoring and feedback control, maintaining column oven setpoints within ±0.3 °C over ambient fluctuations
• Low-volume, high-pressure fluidic path optimized for UPLC pressures up to 15,000 psi, minimizing dwell volume and band broadening
• Acoustically damped mechanical design achieving <65 dB(A) sound pressure level during normal operation—suitable for shared laboratory spaces
• Refurbishment includes replacement of wear-critical components: injection valve rotor seals, syringe plunger O-rings, wash station tubing, and thermal interface materials

Sample Compatibility & Compliance

This ACQUITY Sample Manager accommodates a wide range of sample containers, including 2 mL screw-thread vials, 1.5 mL conical vials, 96-well and 384-well microplates (ANSI/SLAS-compliant), and custom rack-mounted formats. It supports both aqueous and organic solvent-based mobile phases without degradation of sealing performance. The instrument complies with IEC 61010-1 for electrical safety and meets electromagnetic compatibility (EMC) requirements per CISPR 11 Group 1, Class A. While not supplied with factory calibration certificates, its refurbishment protocol includes traceable verification against NIST-traceable temperature standards and volumetric reference standards. Data integrity features align with ALCOA+ principles, and when operated with Empower 3 or later, the system supports audit trail generation and electronic signature workflows compliant with FDA 21 CFR Part 11 and EU Annex 11 requirements.

Software & Data Management

The Sample Manager interfaces natively with Waters Empower Chromatography Data Software (CDS) versions 2 through 4, enabling method-driven temperature scheduling, plate mapping, and sequence-based injection parameterization. All temperature setpoints, injection volumes, and wash protocols are stored as metadata within the acquisition method file, ensuring full traceability. Instrument diagnostics—including thermal sensor readings, valve actuation counts, and syringe pressure profiles—are logged automatically and exportable for preventive maintenance trending. Remote monitoring via Waters Connect is supported when deployed on a local network with appropriate firewall configuration. No proprietary cloud services or subscription dependencies are required for basic operation or data export (CSV, PDF, .raw).

Applications

• High-throughput pharmaceutical QC release testing (e.g., assay, related substances per USP & EP monographs)
• Biopharmaceutical characterization workflows requiring strict thermal control—such as monoclonal antibody subunit analysis or peptide mapping
• Environmental residue screening where cold-chain sample integrity must be preserved prior to injection
• Academic metabolomics and proteomics pipelines leveraging large-scale 384-well plate formats
• Method development labs validating column temperature effects on selectivity and peak symmetry in reversed-phase and HILIC separations

FAQ

Is this unit covered by Waters’ original manufacturer warranty?
No. This is a professionally refurbished unit backed by a 6-month limited hardware warranty administered by SpectraLab Scientific, covering defects in materials and workmanship under normal use.

Does it include the column heater module?
Yes—the integrated column heater is fully functional and calibrated; temperature verification reports are available upon request.

Can it be integrated with non-Waters detectors or mass spectrometers?
Yes, via standard TTL and analog I/O triggers; however, full synchronization and advanced features (e.g., scheduled column heating) require Waters-compatible controllers or Empower CDS.

What documentation accompanies the instrument?
Refurbishment certificate, post-validation test report (including temperature uniformity, carryover, and injection precision data), electrical safety check record, and complete user-accessible service logs.

Is remote technical support available after purchase?
Yes—SpectraLab Scientific provides email and phone-based engineering support during business hours (EST), including method troubleshooting and basic Empower configuration assistance.
