WHAT IS RAMAN SPECTROSCOPY?

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…

MICROPLASTICS ANALYSIS WITH FTIR & RAMAN SPECTROSCOPY

What are Microplastics? A microplastic is a small piece of plastic that is <5 mm in size. Plastics that measure under 100 nm are regarded as nanoplastics. The presence of microplastics in the environment and our food chain is of growing concern. This has led to increased testing for the presence of microplastics in a…

ESSENTIAL TOOLS FOR POLYMER CHARACTERIZATION

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.
