B&W Tek has launched its fully comprehensive website, contentuniformity.com, where users can learn about QTRam® and the benefits of transmission Raman spectroscopy.
On the site, users are able to gain insight into the various ways that quantitative transmission Raman spectroscopy can be used as an asset to content and blend uniformity testing, reference the application note and contact a number of experts ready to help with their application needs.
Quantitative transmission Raman spectroscopy is a variant of Raman spectroscopy where the laser is directed onto the sample from one side and Raman signal is collected from the other side.
Quantitative transmission Raman allows the laser photons to move through the entire body of the sample and the Raman signal collected from the other side conveys molecular spectroscopic information on its volumetric content.
This technology, combined with chemometric modelling, is quickly emerging as a valued technique for nondestructive content and blend uniformity testing due to its high chemical specificity, which is particularly useful when dealing with complex pharmaceutical formulations that contain multiple components.
