Ease of Use, Ease of Science, Ease of Mind The Alliance® HPLC System is the flexible and reliable workhorse that meets your fundamental HPLC separation requirements. The system has been continually expanded and perfected to accommodate an enormous range of real-world analytical challenges. The Alliance HPLC System meets the rigorous requirements of timely and predictable routine analyses in addition to the performance standards of new-product research and development. Alliance systems and columns are manufactured to a rigid set of performance specifications, allowing you to confidently transfer a method between instruments and still get consistent results, unit-to-unit and lab-to-lab. Whether your lab analyzes samples in the pharmaceutical, chemical, food safety, environmental, or quality control arenas, the Alliance HPLC system offers you a field-proven solution. It offers: Integrated solvent and sample management to ensure consistent system-to-system performance and high reproducibility Full integration with either Empower™ or MassLynx™ Software for instrument control and data processing A large, intuitive LCD-based user interface allows rapid system set-up through SystemPREP routines that streamline daily start-ups Easy, tool-free maintenance resulting in maximized uptime Waters complete line of detection technologies – from routine UV/Vis detectors to single, tandem and triple quadrupole mass spectrometers - extend your application capabilities Also available: Alliance HPLC Dissolution Alliance HPLC High Throughput Alliance HPLC Bioseparations
e2695 Separations Module The heart of the Alliance® HPLC System is the e2695 Separations Module and its integrated solvent and sample management functions, which ensure consistent system-to-system performance and high reproducibility. Solvent Management The module’s solvent management system degasses and blends up to four chromatographic solvents in precise proportions for smooth solvent delivery without pulsing. It offers: Serial flow path with only two inlet check valves reduces complexity and minimizes downtime Vacuum degassing uses efficient second-generation polymer membrane technology Precise low-pressure quaternary blending (first in-first out) provides reproducible gradient profiles across the flow range Independently driven pistons produce pulse-free solvent flow without use of pulse dampeners Fixed delay volume (regardless of system backpressure) for consistent, predictable chromatography Programmable flow rate range covers two orders of magnitude (from 50 µL to 5 mL per minute) without hardware modifications Tool-free routine maintenance on plungers, seals, and seal-wash Automated active plunger seal wash Sample Management Up to 120 industry-standard vials can be accommodated in the e2695’s five sample carousels. Sample queues are quick to set up—whether it’s just one sample or a sequence of multiple methods from different analysts. Injections are reproducible from one to hundreds of microliters—compatible with any analytical scale LC column chemistry Variable volume injections eliminate the need to swap loops for analytical methods Carryover is managed by a programmable needle wash cycle and an active needle wash solution (without wash vials) Programmable inject-needle height accommodates various vial geometries and takes into account vial bottom thickness Programmable syringe draw rate for viscous samples/solvents Five independent carousels allow you to run samples in one carousel while prepping the next sequence in another, enabling new samples/carousels to be added into the system—without disturbing the ongoing sample queue Sampling routines for automated reference peak addition or automated pre-column derivitization procedures Tool-free lower seal-wash frit and injection syringe replacement, for easy routine maintenance

|4 System Control Lisence Diskette|
A few years ago I bought a Waters Alliance 2795HT and detectors 2996 and 2475, with a software package Empower2(Enterprise edition) of the website.
I've installed the follow Empower 2 Software (Enterprise edition) and "Base Key Disk", " 5 Named User License Key Disk" and " Concurrent User Licence Key Disk" on my Software on the Server and client systems, and only my "4 System Control License Key Disk", was installed on Seller system, And apparently the seller forgot to remove this diskette, like the other three diskettes from the previous system, And the seller has sold that PC to another customer and no longer has access to it.
please guide and help me.

|Waters 2690_2695 Alliance Pump issue |
Kindly inform us following mentioned service issue and reasons
After that one, it continued by presenting "Solv delivery h/w fault" followed by another one "Plunger homing fault (0)" and it does not initialize.
