The determination of toxic metals Hg, As and Sb in biological samples of humans is an important clinical screening procedure. Exposure of these metals from the diet, local surroundings and industrial & occupational processes can lead to serious and significant health issues.
Analyzing the total concentration of these elements is important but, by no means, the whole story.
Soils are the major sink of these metal contaminants, while in aquatic systems, sediments are the major recipients for these pollutants. With the addition of analyte separation capabilities (which is becoming more routine) allowing for speciation studies, PSA offers powerful analytical tools to help contract laboratories, research teams and regulators alike with these determinations.

The consumption of food and drink is one of the main sources of exposure to toxic metals. Selenium, is an essential nutritional element and is often added as a supplement
to food for health benefits. It is also an important element in animal feed to ensure livestock wellbeing. Coupling Atomic Fluorescence Spectrometry (AFS) with either cold vapour generation or hydride generation has been PSA’s core
competency for over 35 years.
In recent years wastewater treatment plants have been installing technologies to capture and remove the metals. The efficiency of these treatment processes needs to be monitored using accurate analytical systems.PS Analytical offers 2 fully automated online wastewater analysers are PSA 10.226 Online Hg and PSA 10.256 Online Excalibur (for As/Se)

Polymer characterization is important in developing new polymers as well as maintaining quality control in manufacturing processes. As such, many characterization techniques should ideally be linked to the desirable properties of the material, hence analytical techniques are typically used to determine molecular structure, molecular mass / chain length, thermal properties and mechanical properties.
