Thermo Scientific Chromeleon Chromatography Data System (CDS) is used by laboratories in a wide range of different industries around the world. Many of our customers are challenged to improve efficiency and productivity while meeting the ever-increasing demands for regulatory compliance, data integrity and flawless operation.

To better meet the wide range of requirements from our customers, Thermo Fisher Scientific employs a release strategy that provides customers with a choice of how to deploy Chromeleon CDS. Starting with Chromeleon 7.2 CDS SR5 and all subsequent releases, the strategy entails:

  • The Feature Release (FR) channel (major (7.X) and minor (7.X.Y)) introducing new innovations and enabling customers to stay up-to-date with the newest technologies and latest advancements. Maintenance Updates (MU) are released to maintain stability. A given Feature Release is supported until the next major or minor Feature Release.
  • The Long-Term Support (LTS) channel provides a base Chromeleon version enabling customers to maintain utmost stability and robustness over an extended period with minimized validation efforts. Maintenance Updates (MU) are released regularly. These updates include fixes for high priority defects that can be made with a low risk for compromising stability.
  • The Extended support (-ES) channel provides a base Chromeleon software version enabling customers to use newer functionality than the LTS channel whilst focusing on maintaining stability. Maintenance Updates (MU) are released regularly.
