What is a Raman probe?

raman probe definition

Raman probe is the device used in Raman spectroscopy to connect the spectrometer to the sample. There are three common probe types that provide flexibility in the sample interface. These are for immersion, non-contact, and flow. The most common configuration is the immersion probe designed to be inserted into a reactor containing the reaction sample. If the chemistry is corrosive or needs to be sealed, it is often preferable to use a non-contact Raman probe positioned outside of a site window looking into the reactor. For flow applications, the flow cell can be coupled in-line to make continuous measurements.   

How do you use a Raman probe?

Simply connect the Raman probe SmartConnector to the spectrometer base unit. Then considering the type of sample to be measured, connect the sample interface end of the probe — an immersion probe into a reactor, a flow cell into a bypass loop or flow path, and a non-contact Raman optic at a site glass or window to remotely observe the reaction. Once the connection is complete, use iC Raman software to optimize the data acquisition parameters and set up the experiment profile.

Is Raman or FTIR better for my application?

Raman and FTIR spectrometers both provide molecular information about the structure and composition of chemical and biological samples. Due to the fundamental principles that govern each of these vibrational techniques, the spectra are different and as a result, it is considered that they provide complementary information. Frequently one technique will prove a better choice, depending on the nature of the application.
