Introduction to Waters HPLC Alliance e2695

The Waters HPLC Alliance e2695 is a core module of the Alliance HPLC system, manufactured by Waters Corporation (USA). Renowned for its high efficiency, reliability, and flexibility, it is widely used in pharmaceuticals, chemicals, food safety, environmental monitoring, and other fields.

Key Features

1. High-Performance Separation

   • Utilizes CORTECS 2.7 μm columns, bridging the performance gap between HPLC and UPLC for enhanced resolution and throughput.

2. Integrated Design

   • Solvent Management System:
     • Supports quaternary gradient mixing with a flow rate range of 0.010–10.000 mL/min (±1% accuracy).
     • Features automatic degassing and compressibility compensation for pulse-free solvent delivery.
   • Sample Management System:
     • 120-position autosampler with an injection volume range of 0.1–100 μL (expandable to 2000 μL).
     • Ultra-low carryover (<0.0025%) for high-precision analysis.

3. Exceptional Reproducibility

   • Ensures consistent inter-system performance, enabling seamless method transfer without revalidation.

Technical Specifications

• Flow Rate Precision: ≤0.075% RSD, gradient precision ±0.15%.
• Column Oven: Temperature range 4–65°C, supports three columns simultaneously.
• Detector Compatibility: Compatible with UV, fluorescence (FLR), mass spectrometry (MS), and other detectors for versatile applications.

Operation & Maintenance

• User-friendly LCD interface and SystemPREP program for simplified startup.
• Compatible with Empower™ and MassLynx™ software for automated control and data processing.
• Modular design allows tool-free maintenance (e.g., piston seal replacement), maximizing uptime and efficiency.

Applications

Ideal for:

• Pharmaceutical R&D & QC
• Environmental pollutant analysis
• Food safety testing
• Analysis of high-boiling-point and thermally labile compounds

With its proven performance and continuous innovation, the Alliance e2695 remains a benchmark instrument for high-performance liquid chromatography (HPLC) in modern laboratories.
