Flow Meters and Controllers for Elemental Analysis

When and Why Are Trace Elements Measured?

Measuring trace elements is essential in many fields. Environmental analyses, for instance, require monitoring heavy metals like mercury, lead, cadmium, and arsenic to protect human health and ecosystems. Even common elements such as carbon or sulfur can be significant when their levels change, indicating environmental shifts or industrial issues.

Pharmaceutical companies also rely on TEA to ensure product purity. The need for precision and consistency drives the demand for advanced flow solutions. Our team works closely with customers to tailor flow meter and controller configurations that meet their specific analytical requirements.

I enjoy contributing to a cleaner and safer world by enabling more accurate data collection through analysis devices, often in collaboration with other manufacturers.

What Role Do Flow Controllers Play in Elemental Analysis?

During elemental analysis, samples are separated and detected using specialized equipment. A carrier gas transports the components, while other gases may be used for chemical reactions to help identify the elements being measured. These gases must be ultra-pure, and the flow control systems must be both accurate and highly reproducible to ensure consistent and reliable results.

This level of precision is crucial—results must remain consistent, whether the test is performed in a lab or at a remote location like a mountain in Switzerland.

What Are the Specific Needs in Elemental Analysis?

Flow meter and controller requirements vary widely depending on the device design, signal processing, control systems, power supply, and cost. Our engineers work closely with customers to ensure that the chosen solution fits their unique application.

Collaboration between our teams and those of our clients leads to innovative and effective outcomes.

Bronkhorst flow controllers already support self-diagnosis to monitor instrument conditions. We are also exploring predictive maintenance features, such as analyzing valve tension to anticipate potential issues.

I’m currently working with pharmaceutical companies to understand their specific needs in trace elemental analysis. I’d love to hear from readers who have thoughts or questions on this topic!
