Raman spectroscopy is an established spectroscopic technique for measuring the chemical identity and structure of materials across many industries, including pharmaceuticals, fine chemicals, minerals and foods.
Raman spectroscopy has a very high chemical specificity and is routinely used to differentiate between different polymorphs of the same compound for example. When used in conjunction with static image analysis it provides a powerful means of measuring the chemical identity of individually dispersed particles within a sample.
Applications of this technique include:
- Chemically specific particle characterization of ingredients in mixtures
- Identification of contaminants or outlier particles
- Quantification of chemical composition in mixtures by particle count.
