Raman spectroscopy combines exceptional specificity with tremendous ease of use – perfect for identifying unknown substances. The principle is simple: a laser is directed at the sample, the scattered light is collected by the spectrometer, and processed into a unique Raman spectrum, much like a fingerprint. With no sample preparation required, this method is increasingly becoming the preferred solution for rapid analysis. In this article, you’ll learn exactly how such “identification” works and get a practical guide to spectral searching using Wasatch Photonics' ENLIGHTEN software. Whether you’re new to Raman spectral comparison or looking to build a customized spectral library for your application, this is the perfect place to start.
