Test & measurement


goes into the complex process of machining as well as the quality of the surface finish. Mass produced valve blocks may not have the optimum level of quality or the best design features for a particular application. It is better to have a range of options for materials and valves to ensure the most effective design is achieved. For example, incorporating pulse valves enables solvent bottles to be changed during operation, saving time for operators. In the same design, cleaning processes can be automated and valve blocks designed to optimise this activity as well.


COMPACT RELIABILITY A similar situation exists for gas chromatography as well. Designing and building analysis equipment for laboratories is a complex task, needing to combine a compact footprint with precision, speed of analysis and reliability. As a manufacturer, sourcing all the various components to create a gas control solution, as well as configuring and installing them can be a painstaking process.

This can be made much simpler by engaging with an expert in the field, such as Bürkert, that has the expertise to design, specify, source, assemble and test all the required components. The result is a task-specific device, optimised for performance and reliability, that delivers stable measurement results with excellent repeatability. Furthermore, the gas control system can be designed with simple integration interfaces to match both the mechanical and electronic/communication protocols. More complex systems can include multi-channel mass flow controllers, bespoke manifolds and integrated control systems, all of which can be developed and supplied by specialists such as Bürkert.


PRECISION RESULTS


Chromatographs offer clinical and pharmaceutical laboratories the means to conduct vital research and development work. The precise control of gas and liquid flow in chromatography is paramount to obtaining reliable analytical results. Overcoming the challenges in developing new chromatographs requires a multifaceted approach,


incorporating advanced technologies and innovative solutions.


By addressing these topics with the support of experts such as Bürkert, the pharmaceutical and clinical sectors can continue to rely on chromatography for critical analyses, ensuring the safety and efficacy of drugs as well as the accuracy of clinical diagnostics.
