Harmonisation of Analytics Systems: Advantages of a standardised CDS platform
In modern analytical laboratories, the harmonisation of systems is crucial for efficiency and accuracy. A harmonised chromatography data system (CDS platform) connects different analytical systems and reduces the administrative and regulatory burden. Numerous benefits can be realised by implementing such a platform.
Analytical laboratories often start with just a few devices and specific applications. Stand-alone systems offer seemingly cheap and quick solutions. Each instrument is operated with individual software for control and data processing, which initially seems manageable. However, the challenges become apparent as the laboratory grows and the number of instruments and the range of analyses increases. Individual workstation systems then cause increased administrative effort and require digital harmonisation.
A standardised CDS platform enables cross-device administration and facilitates connection to a laboratory information management system (LIMS). This leads to synergy effects and reduces the learning and administrative effort. Manual data transfers are also minimised, which reduces potential sources of error and effort.
A significant advantage is the centralised management and storage of all data on a secure database server. This eliminates the parallel workload of individual workstation systems. All measurement data, methods, calibrations and reports are stored centrally, which increases data integrity and fulfils regulatory requirements more easily.
CDS Platform: Flexible and Efficient Work Processes
A client-server CDS enables flexible working from the entire network. Instruments can be controlled remotely via mobile devices such as laptops or tablets, and the progress of analyses can be monitored regardless of location. Processing, checking and reporting of all data is therefore also possible from the home office. This flexibility increases efficiency and enables better customisation to the laboratory’s work processes.
The client-server system is modularly expandable and can integrate a wide range of instruments. This includes chromatography, spectroscopy and mass spectrometry instruments as well as devices for elemental analysis. Each control computer (ACQ) controls the instruments, while system and data management as well as post-run functionalities are carried out via clients. A terminal server also allows comprehensive system and data management and access via office computers without the need to install CDS software.
A bidirectional UMS connection is possible either via a direct connection to a programming interface or a file-based exchange. File-based exchange is easily configurable within the CDS software. Batch files are created in text format, loaded into the CDS database and converted into the appropriate format. Data files are then reformatted and read into protected directories for the EMS.
