Sometimes referred to as a chromatography data system (CDS), a chromatography data management system (CDMS) is a set of dedicated data-collection tools that interface and/or integrate with a laboratory's chromatography equipment. A base CDMS will set up a desired methodology to be used by the chromatography equipment, acquire data from it, process the acquired data, store the information in a database, and interface with other laboratory informatics systems to import and export files and data.[1]

History of the CDMS

The first attempts to automate the analysis of chromatography data through electronics took place in the early 1970s. These analysis tools utilized microprocessor-based integrators, "dedicated devices for measuring chromatographic peaks and performing user-specified calculations" which also featured a printer plotter to output the results.[1] Limited memory plagued those early systems, preventing more than one chromatograph from being stored at any one time. This became less of problem for large labs with bigger budgets in the mid-1970s, as expensive centralized data systems were installed, allowing greater data storage and sharing capabilities.[1]

As computers shrank in size, the personal computer became a viable reality. In 1980, entrepreneur and Hewlett-Packard prodigy Dave Nelson saw the potential the personal computer could have on the field of analytical chemistry, joining with partner Harmon Brown to create Nelson Analytical Inc. That year they developed the first CDMS personal computer software, soon followed by Turbochrom, the first CDMS system for MS Windows.[2][3] This innovation quickly spread from analytical chemistry labs to the fields of environmental, forensic, and pharmaceutical sciences. At the same time chromatography minicomputers like Hewlett-Packard's 3350 LAS Lab Automation System and Perkin-Elmer's LIMS 2000 CLAS chromatography laboratory automation system were seeing increased utilization, featuring the data acquisition and processing of up to 32 or more simultaneous chromatographs.[4]

In the 1990s, more affordable higher-performance PCs — combined with tighter networking standards — allowed for networks of CDMSs, especially those installed on personal computers. By the late '90s, the CDMS commonly featured the ability to set up a methodology and analytical run information, control some instruments, acquire injection data, process the data in different ways, save the data, and transmit it to other systems like a LIMS.[1] At the turn of the century the CDMS was becoming increasingly web-enabled[5], and by 2008, CDMS functions were becoming more enhanced, driven by improvements in liquid chromatographs (LC) and gas chromatographs (GC). The new innovation of high-speed LC and GC instruments meant the potential for faster data generation, improved separation, and higher resolutions and sensitivities.[6] While these next-generation machines would bring more processing power to chromatography labs, it also meant that vendors would have to improve CDMSs, specifically the analog-to-digital converter sampling rates. Some vendors were estimating at the time that data acquisition sampling rates on the order of 100 to 300 Hz would be needed to keep up with the new wave of speedier chromatography devices. Additional concerns of scalability and remote access were becoming important due to the expansion of pharmaceutical and chemical companies expanding into parts of Latin America, South America, and the Far East.[6]

Features of a CDMS

A CDMS may be set up for use in three primary ways[7]:

  • as a standalone system that controls two or more chromatographs
  • as a standalone system that controls a single chromatograph, including LC-MS or GC-MS instruments
  • as a networked system that controls multiple instruments in one or more labs

In operation, a CDMS provides multiple features, including (but not limited to)[7][8]:

  • sample and blank processing
  • integration of peaks and construction of calibration curves
  • data analysis, visualization, and validation
  • third-party software integration
  • third-party instrument integration
  • data warehousing from multiple instruments
  • workflow management
  • procedure and experiment development and scheduling
  • out-of-specification and out-of-tolerance testings
  • audit trail and compliance control
