The core of the Alliance system is the Waters 2695 Separation Module. The 2695 is based on the advanced integrated solvent and sample management architecture of the 2690 Separation Module, with numerous design innovations addressing users' critical needs. The 2695 separation unit in the Alliance system is designed to work seamlessly with Empower / MassLynx software and includes Symmetry and Xterra columns, along with a variety of optional detectors (including Micromass ZQ? and Quattro micro? mass spectrometry detectors). The entire system is supported by Connections? (Waters' exclusive service support program) to achieve optimal performance and efficiency. This is the reason for its reliable performance and excellent reproducibility, ultimately leading to high-quality results and increased uptime.

Laboratories require 24/7 continuous operation, placing higher demands on instrument durability and reliability. With rising costs, lab managers are constantly seeking ways to reduce maintenance time and improve operational efficiency. It has become increasingly important for instruments and software to deliver uninterrupted daily operation while providing the highest quality results. To meet these demands, Waters has introduced significant design innovations over the earlier 2690, 2690D, and 2790 separation modules (the core of the Alliance system), incorporating many new technologies that were not available at the time of their 1996 release. This has resulted in a new generation of superior instruments.
