The consistency of the Alliance HPLC System gives you exceptional confidence in your analytical results, day-to-day and year-to-year.

Get accurate and reproducible results with Waters' flagship HPLC technology, which provides consistent and reliable performance whether your Alliance HPLC System is newly manufactured, or you're working on one that is several years old.

Comparison of the separation of carbamates using two different Alliance HPLC Systems, manufactured 7 years apart. The results are equivalent.

• Quaternary solvent blending supports isocratic and gradient applications with 11 unique gradient profile curves. Blend up to 4 solvents in any proportion with Auto-Blend Technology. Compatible with a wide range of solvent types to support reversed-phase, normal-phase, GPC, SEC, and IEX application.
• Advanced solvent delivery capabilities. Serial flow path with pulse-free solvent delivery without the use of dampeners. Online solvent degassing and automated solvent compressibility for accurate flow. Integrated seal wash for robustness operation with all solvent types is standard.
• Up to 120 vials housed in an optional, temperature-controlled environment.  Active and user programmable needle wash for low carryover.  Variable injection volumes from 0.1 to 100 uL standard, and up to 2 mL optional.  Supports STAT samples and auto-addition.
• Optional column heating or heating/cooling. Get the flexibility of running multiple methods on demand with optional column switching.
• Detection capabilities include photodiode array, UV/Vis, fluorescence, refractive index, evaporative light scattering, electrochemical, conductivity, and mass detection.
• An intuitive user interface, giving you instant access to system settings through the large LCD screen. Simplified daily set-up with SystemPREP.
• Supported in Empower, MassLynx, and several 3rd party software packages
• Compliance-ready. Qualification of laboratory instrumentation is an integral part of compliance with regulatory and quality standards such as GMP, GLP, ISO 17025, USP <1058>, and others.  The Alliance HPLC System supports Waters Empower-based automated system qualification tool (SQT), which minimizes the time and cost associated with annual qualification.
