Advancing the clinical translation of medical Raman techniques

In this webcast, we look at the potential of optical techniques, primarily Raman spectroscopy, in medical diagnostics - and the barriers to clinical translation. Details are given on the development of components and systems for use in monitoring antibiotic resistance, for example, as well as in cancer diagnosis and detecting viruses.

Fast Raman Hyperspectral scanning of mining core samples

Long wave infrared (LWIR) spectroscopy is of great interest to spectral geologists. This is because minerals such as quartz, k-feldspar, pyroxene, hornblende, anorthite, calcite, and dolomite are only identifiable in the LWIR range, not in the short-wave infrared (SWIR) range. However, Raman spectroscopy is complementary to LWIR spectroscopy, providing fingerprint spectra of these minerals and an alternative identification method. But Raman spectroscopy also provides several additional benefits on the instrument side.

Authentication of Pisco: From origin to alcohol content with Raman

This article is brought to you by: 

Raman spectroscopy is emerging as a rapid, portable tool to test premium liquors for evidence of adulteration or substitution –problems relevant in the rising production of pisco in Peru, where the liquor must originate from specific grape varieties and regions. Here we demonstrate the ability of 1064 Raman to distinguish pure pisco from mixtures, identify the specific grape variety, and quantify both ethanol and methanol content with a high degree of accuracy – thus validating origin, quality, and safety.
