Chromeleon SDK specifications

Importance of the Topic

The Chromeleon Software Development Kit (SDK) provides a versatile interface for integrating and extending chromatography data systems within modern analytical laboratories. By enabling seamless connectivity between Chromeleon CDS and external applications—such as LIMS, ELNs, or automation platforms—it addresses the growing need for flexible, automated data workflows and custom analytical tools.

Objectives and Overview

This document outlines the specifications of the Chromeleon SDK, distinguishing between out-of-process and in-process extensions, detailing licensing and certification requirements, describing developer prerequisites, and summarizing the key CDS functions accessible via the SDK API.

Methodology and Instrumentation

The SDK consists of a .NET-based API designed for Windows environments. Development is accomplished in C# using Microsoft .NET Framework 4.x and Visual Studio 2012 or newer. Two application models are supported:

• Out-of-process (.exe) extensions: standalone executables that interact with Chromeleon CDS without altering its UI. No runtime license or certification is required.
• In-process (.dll) extensions: plugins loaded into the Chromeleon Client to augment menus and features. These require both an SDK Runtime license and certification by the CDS SDK team.

Used Instrumentation

The SDK interfaces exclusively with the Thermo Scientific Chromeleon Chromatography Data System (CDS) installed on Windows clients. It leverages the CDS object model to perform tasks such as sequence management, instrument control, data retrieval, and reporting.

Main Results and Discussion

The specification tables enumerate supported functions, including silent logon, data vault navigation, sequence and injection handling, real-time instrument monitoring, method management, raw data and result access, and import/export operations. Licensing details and development requirements are clearly mapped to application types. The guidelines emphasize the importance of leveraging experienced partners for initial SDK adoption and outline Thermo Fisher’s support boundaries.

Benefits and Practical Applications

• Custom automation of chromatography sequences and data acquisition.
• Integration with laboratory information management systems and electronic lab notebooks.
• Development of bespoke user interfaces for targeted workflows.
• Enhanced reporting and data exchange capabilities within existing IT infrastructures.

Future Trends and Applications

As laboratories continue adopting digital transformation, SDK-driven integrations will expand to cloud-based services, web-enabled multi-user platforms, and advanced data analytics tools. AI-powered post-acquisition processing and real-time decision support are emerging areas for SDK extension.

Conclusion

The Chromeleon SDK represents a robust framework for extending and integrating chromatography data systems into custom software solutions. Its clear licensing model and comprehensive function coverage enable developers to build tailored applications that improve laboratory efficiency and data interoperability.
