Distinguishing between similar materials, including real and fake whiskies, with Raman spectroscopy and data classification
Raman spectroscopy is excellent for distinguishing between materials. In many cases you can distinguish them by looking for the presence of certain Raman bands. Other times you can match the spectra to a combination of spectra from a library, or by using a least-squares optimisation. However, if the materials are chemically very similar, the variations between their spectra are too complex and subtle for these simple methods.
We will discuss the classification methods you can use to distinguish similar materials and show how Renishaw’s Data Classifier software has the potential to diagnose diseased brain tissue and can distinguish between real and fake whiskies. We will show how you can build classification models and quantify sensitivity and specificity.

Patrick Kubryk, Raman Applications Scientist
Patrick has been working for the spectroscopy applications team at Renishaw since 2017. His PhD in analytical chemistry, with a focus on the spectroscopy of micro-organisms, gives him a strong background in Raman spectroscopy. His interests today are on the broad application of Raman spectroscopy to all scientific and industrial fields.
Tim Smith, Raman Applications Manager
Tim has over 20 years' experience using a range of Raman research instruments. He has extensive knowledge and real-world use of systems in most application areas, however, his particular expertise is within Raman imaging and pharmaceutical applications.
