Raman systems and the eternal problem of fluorescence by Dr Enrique Lozano & Dr Yaroslav Aulin Overview In the field of spectroscopy, Raman spectroscopy to be precise, the perpetual element that seems to find its way into every Raman related conversation is fluorescence, code name: "Raman's natural enemy". When [...]
The benefits of multichannel Raman spectroscopy in art conservation by Dr Enrique Lozano Overview Raman spectroscopy is a powerful analytical technique that in recent years has gained significant recognition in the field of art conservation and that is being utilised by numerous institutions worldwide, helping to advance [...]
Using a small footprint multichannel Raman system for the fluorescence analysis of synthetic zultanite by Dr Yaroslav Aulin & Dr Enrique Lozano Overview Fluorescence is what Raman spectroscopy users continuously fear. The activation of fluorescence process while acquiring a Raman spectrum means that it is likely that [...]
Our Lead Scientist, Dr James Thomson has recently met with the Raman spectroscopy audience to discuss how Raman spectroscopy practices ensure good data. Here you can view the recording of the live webinar hosted by Yordas Group and Dr James Thomson on the 25th of March 2022. The webinar provides Raman operators with guidance [...]
Calibration and Validation of Raman Instruments What does it mean, and do I have to? Overview Within our series of papers on harmonisation in Raman spectroscopy, we continue to describe how the calibration and validation of Raman data is achieved. Raman Spectroscopy is a very powerful technique for [...]
The Need of Harmonisation in Raman Spectroscopy? CHARISMA - a European initiative to normalise industrial use of Raman - by Dr Enrique Lozano Overview Raman spectroscopy is a technique that involves scattering of monochromatic light, first observed by Sir C.V. Raman (i), after whom this technique is named. [...]
Dual laser Raman analysis of glass Overview Raman spectroscopy is a powerful tool for the analysis of ceramics, glasses, pigments, dyes, gemstones, etc. which are of significant regard in art and archaeology. Specifically, the ability of Raman spectroscopy to differentiate between very similar samples. During an assessment of a [...]
Why Raman Spectroscopy? Overview For identification and authentication purposes, the use of fundamental vibrational techniques is preferred to other techniques (e.g. chromatography) when possible, because results are easily reproducible, data contains information linked directly to physical and chemical properties, the limits of detection (and/or product deviations) are in general [...]
