Application Note: Raman Analysis of Pharmaceutical Ingredients
Posted: 12 January 2015 | Ocean Optics
A range of options is available for Raman analysis, including systems suitable for handheld, laboratory and educational applications. Systems typically include a spectrometer, laser, operating software and sampling accessories, while modular options are available for users to configure their own Raman systems. Setups are available for various wavelength ranges and resolution requirements.
Raman spectroscopy offers a number of benefits for testing and characterisation. It is rapid and non-destructive, requires only limited sample preparation and allows for sample volumes in the microliter range. In addition, Raman can be used to measure aqueous samples or samples with high moisture content, and allows researchers to capture data from a sample contained in plastic or other materials that are optically transparent to the wavelengths of interest. Raman is particularly useful for pharmaceutical applications. For example, Raman techniques are used to discern characteristics of pharmaceutical raw materials, including active ingredients, binders, fillers, lubricants and other excipients. Raman is also useful for through-container measurements of pharmaceutical blister packs, pill bottles and vials.
