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.

Raman spectroscopy is a molecular analysis technique that has been adopted by industrial, forensic, environmental and research scientists to: • Identify and quantify unknown materials (e.g., Forensic evidence, art restoration) • Understand molecular structure (e.g., crystallinity, polymorphism) • Study spatial relationships between sample components (e.g., failure/defect analysis, depth profiling) Advantages of Raman Spectroscopy You may…

Here is a list of common test methods used to evaluate plastics. They tell you how to check tensile and flexural properties, stiffness, impact, hardness, flammability, etc. Where applicable, ASTM specs are given as sources for more detailed information.

When we talk about “Dynamic Contact Angle” (DCA), there are two quite different subjects that may be addressed:
– Time-Dependent Contact Angle (tDCA)
– Motion-Dependent Contact Angle (mDCA)

How Does Melt Flow Indexer Works? It heats and compresses thermo-softening resin, then measures resin extrusion rate through an orifice, under carefully carefully controlled conditions such as..
