Individual spectral ‘fingerprints’ of materials can be obtained using Raman Spectroscopy. The technique is widely used in the pharmaceutical, chemistry, and medical fields, to provide information which allows molecules to be detected.
To provide Avantes customers with optimal performance for a reasonable price, the company has partnered with two other companies to offer three different Raman Bundles, an exceptional software package to test the Raman spectra, and a unique Laser-Probe combination (785 nm) to supply enhanced signals.
Type of Measurements
Raman methods are used for several different materials. The Avantes bundles are excellent for studying liquids and powders. When strong signals are present (alcohol-based liquids, aromatic compounds), in general Ava-Raman-A is ideal for performing measurements.
When weak Raman signals occur (integration time longer than five seconds), using the thermo-electric-cooled (TEC) spectrometer is advised. This is included in the Ava-Raman-B bundle. If very weak signals are present possibly together with fluorescence background, Ava-Raman-C is advised for use (higher quantum efficiency in NIR and improved signal to noise performance).
