Precise detection of toxic metals in food and environmental samples

P S Analytical (PSA) is a leader in providing high-performance analytical instruments for detecting mercury, arsenic, selenium, antimony, and bismuth in various sample matrices, including environmental and food and beverage samples. The presence of these toxic metals in different forms poses significant health and environmental risks, making their detection a growing priority.

PSA’s solutions meet the increasing demand for both total and speciated analysis, which presents analytical challenges in terms of sensitivity, selectivity, and interference management. The company offers a range of tools designed to address these challenges, ensuring highly accurate and reliable results.

For over 30 years, PSA has been at the forefront of Atomic Fluorescence Spectroscopy (AFS), utilising cold vapour and hydride generation for trace metal analysis. The company has further expanded its capabilities by integrating analyte separation, enabling speciation studies that distinguish between harmful and less toxic forms of metals.

Applications include the separation of methyl mercury from inorganic mercury in water, seafood, dairy, and grains, as well as the identification of inorganic arsenic in comparison to organic arsenic species in food items like rice and seaweed. These advances are vital for monitoring the safety of food products and environmental samples.

PSA continues to develop new methods to address emerging concerns and is open to collaborating with researchers and organisations to explore additional applications. With thousands of systems in operation across Europe, the USA, and Southeast Asia, PSA offers a reliable combination of performance, affordability, and excellent customer support.
