Raman spectroscopy

The ideal tool for material identification.

Raman spectroscopy can be used to effectively and efficiently identify and distinguish between different materials in liquid and solid forms, including organic materials and polyatomic inorganic materials (e.g. oxides and polyatomic salts like phosphates, sulphates etc.) The identification can be accomplished in as little as 20 seconds from collection of data to analysis report. Packaging materials such as polymer bags, glass bottles, flasks and vials do not interfere with the measurement, allowing the user to screen materials by non-contact, non-destructive analysis, without needing to open containers.

Raman spectroscopy is a vibrational technique so any chemical or physical changes that affect the molecular vibrations will change the Raman spectrum including degree of crystallinity, hydration and polymorphism, extending the technique usefulness to the identification of counterfeits and patented formulations infringement. In addition, unlike other vibrational spectroscopies such Fourier transform infrared (FTIR), water has relatively weak Raman peaks which allows Raman to measure samples that are hydrated or in aqueous solutions.

The specificity of Raman, which allows rapid creation of new materials databases and methods, and its relative ease of use have made Raman spectroscopy a popular technique when chemical identification and material inspection is required. Portable and handheld Raman devices are now used for a broad range of applications including pharmaceutical and biopharmaceutical analysis, safety and security and food.
