Whether you are expanding your laboratory capacity, have increasingly challenging assays, or have greater throughput requirements, the Alliance HPLC System has many optional accessories designed to extend the system’s capabilities to fit your changing business needs.

Waters Alliance e2695 Separations Module is a high-performance liquid chromatographic system with a quaternary, low-pressure mixing pump and inline vacuum degassing. Flow rates from 50 uL/min to 5 mL/min can be generated for use with 2.1 mm ID columns and larger.

• Time-tested, dependable, and robust workhorse for your HPLC separations
• Integrated solvent and sample management with consistent system-to-system performance and high reproducibility
• Simplify your daily LC system start-up with advanced software functionality

The autosampler has a maximum capacity of 120 vials (12×32, 2-mL) with programmable temperature control from 4 to 40°C. A heated column compartment provides temperatures from 5 degrees above ambient to 65°C. The detector is a photodiode array (model 2996) with a wavelength range of 190-800 nm and sensitivity settings from 0.0001-2.0000 absorbance units.

Waters Alliance e2695 Features and benefits

• Quaternary solvent blending. Support isocratic and gradient applications with 11 unique gradient profile curves and blend up to 4 solvents in any proportion with Auto-Blend Technology. Compatible with solvent types such as reversed-phase, normal-phase, GPC, SEC, and IEX.
• Advanced solvent delivery capabilities. Serial flow path with pulse-free solvent delivery without the use of dampeners. Online solvent degassing and automated solvent compressibility compensation for accurate flow. Integrated seal wash for robust operation with all solvent types is standard.
• Optional, temperature-controlled environment. House up to 120 vials in an optional, temperature-controlled environment. Achieve low carryover with active and user-programmable needle wash. Variable injection volumes from 0.1 to 100 μL standard and up to 2 mL optional. Support STAT samples and auto-addition.
• Detection and column options. Get optional column heating, heating/cooling, or column switching capabilities. Detection capabilities include photodiode array, UV/Vis, fluorescence (FLR), refractive index (RI), evaporative light scattering (ELS), electrochemical, conductivity, and mass detection.
• Intuitive interface and software. Get instant access to system settings through the large LCD screen with simplified daily set-up with SystemPREP. Supports Empower, MassLynx, and 3^rd party software packages.
• Compliance-ready. Supports Waters Empower-based automated system qualification tool (SQT), minimizing the time and cost of annual qualification with standards like GMP, GLP, ISO 17025, and USP <1058>

The e2695 Separations Module has integrated solvent and sample management and includes both a sample heater/cooler and a column heater. The system features quaternary solvent delivery and sample introduction via a direct inject sample manager. The system may be configured for a broad range of applications supported by HPLC optical detectors and mass detectors, with a choice of instrument control and data management software.

The Waters™ e2695 Separations Module, with its integrated solvent and sample management capabilities, provides the flexibility and ruggedness needed to accommodate an enormous range of HPLC System separation challenges.
