Confocal Raman imaging and related techniques continue to increase in popularity. This whitepaper describes five key factors to consider when evaluating instrumentation: speed, sensitivity, resolution, modularity and upgradeability, and combinability.
Keely Portway looks at how researchers and commercial entities are developing Raman technology to benefit medical applications
Nanoelectronics research hub, Imec, has developed an on-chip solution for Raman spectroscopy, which it says could be integrated into smartphones. The technology is on display at SPIE Photonics West
Advances in Raman spectroscopy could one day make invasive blood glucose tests a thing of the past
The Confocal Raman Imaging Symposium, which took place for the 15th time in Ulm, was like a big family reunion with both familiar and new faces
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.
Princeton Instruments has released a set of 532nm Raman accessories for its easy-to-use, aberration-free Fergie spectrometer
