Chemical identification of particulates
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.
