Waters Breeze™ 2 High-Performance Liquid Chromatograph

Overview

The Waters Breeze™ 2 High-Performance Liquid Chromatograph is a modular, entry-level HPLC platform engineered for routine analytical laboratories requiring robustness, regulatory readiness, and method transfer compatibility across academic, quality control, and contract research environments. Built upon Waters’ decades of chromatographic expertise, the Breeze™ 2 system employs high-pressure liquid delivery, precision solvent mixing (in gradient-capable configurations), and thermally stabilized flow paths to ensure retention time reproducibility and peak shape fidelity. Its architecture supports both isocratic and binary high-pressure gradient elution, enabling method development scalability from screening to validation. The system complies with fundamental chromatographic principles defined in USP , ISO 17025, and ASTM D7372, and its software infrastructure supports audit trail generation and user access control—key prerequisites for GLP and GMP-aligned workflows.

Key Features

• Modular pump options: 515/1515 isocratic or 1525 binary high-pressure gradient pump modules, each rated to 6000 psi and delivering flow accuracy ±0.2% RSD at 1 mL/min
• Autosampler with 96-position tray capacity, supporting programmable injection volumes from 0.1 µL to 10 mL with low carryover (<0.01%) and temperature-controlled sample compartment (optional)
• Expandable detection suite: Interchangeable detectors including 2489 UV/Vis, 2998 Photodiode Array (PDA), 2475 Fluorescence (FLR), 2414 Refractive Index (RI), 2424 Evaporative Light Scattering (ELSD), 2465 Electrochemical (ECD), and 432 Conductivity detectors
• Column oven support with temperature range –10°C to 85°C (dependent on selected module), ensuring retention time stability across ambient fluctuations
• Integrated pressure monitoring and real-time flow calibration, enabling automatic leak detection and system diagnostics
• Front-panel LCD interface with intuitive menu navigation and status feedback for rapid troubleshooting without PC dependency

Sample Compatibility & Compliance

The Breeze™ 2 accommodates standard 3.9–4.6 mm ID analytical columns and 10–21.2 mm ID semi-preparative columns, compatible with reversed-phase (C18, C8), HILIC, ion-exchange, size-exclusion (GPC/SEC), and carbohydrate-specific stationary phases. It meets essential compliance requirements for regulated environments: data integrity features align with FDA 21 CFR Part 11 (when used with Empower™ 3 Software), and hardware design conforms to IEC 61010-1 safety standards. Detector wavelength accuracy is traceable to NIST-certified standards; photometric linearity is verified per USP . System suitability testing (SST) parameters—including tailing factor, resolution, and %RSD of retention time—are fully reportable within the software framework.

Software & Data Management

Operation is managed via Waters Empower™ 3 Chromatography Data System (CDS), a validated, multi-user client-server platform supporting instrument control, sequence scheduling, peak integration, and customizable reporting. Empower™ 3 provides full electronic signature capability, role-based permissions, and immutable audit trails compliant with ALCOA+ principles. Raw data files (.raw) are stored in a secure, timestamped repository with automatic backup configuration options. Integration with LIMS and ERP systems is supported through standard ODBC and XML interfaces. Method transfer between Breeze™ 2 and higher-tier Waters systems (e.g., Alliance, ACQUITY UPLC) is facilitated by shared method templates and consistent detector response calibration protocols.

Applications

The Breeze™ 2 serves as a foundational platform for pharmaceutical assay validation (e.g., content uniformity, dissolution testing per USP ), food safety analysis (mycotoxin quantification, pesticide residue screening), polymer characterization (Mw/Mn determination via SEC/GPC), natural product profiling (flavonoid separation in botanical extracts), and environmental monitoring (PAHs, phenols in water matrices). Its semi-preparative capability (up to 22.5 mL/min, 10 mL injection) supports early-stage compound purification for structure elucidation. In educational settings, its transparent hardware layout and simplified software interface facilitate hands-on instruction in chromatographic theory, method optimization, and detector selection criteria.

FAQ

Is the Breeze™ 2 compatible with modern regulatory data integrity requirements?

Yes—when configured with Empower™ 3 CDS and appropriate IT controls, it satisfies 21 CFR Part 11, EU Annex 11, and WHO TRS 996 expectations for electronic records and signatures.
Can I upgrade from an isocratic to a gradient system later?

Yes—the modular design allows field-installation of a 1525 binary gradient pump and associated solvent manager without replacing the controller or autosampler.
What column oven options are available?

Waters offers the Column Manager CM-100 (–10°C to 85°C, Peltier-cooled) and CM-150 (ambient to 85°C, resistive-heated), both with dual-column switching capability.
Does the system support method validation per ICH Q2(R2)?

Empower™ 3 includes built-in tools for precision, accuracy, linearity, LOD/LOQ, and robustness assessment, aligned with ICH Q2(R2) guidance for analytical procedure validation.
Are replacement parts and service contracts globally available?

Waters maintains authorized service centers in over 30 countries, with spare parts inventory and certified field engineers supporting multi-year warranty extensions and preventive maintenance programs.
