Olive Oil Assessment with Uv-Vis Spectroscopy
December 16th 2024Olive oil, especially extra virgin, is prized for its quality and purity. However, fraud and adulteration are significant concerns. UV-Vis spectrophotometry is a reliable technique for assessing olive oil quality by quantifying key compounds. An Edinburgh Instruments DS5 Spectrophotometer is used to evaluate olive oil quality and detect adulteration.
Spectra, Lifetime & Quantum Yield of Upconversion Nanoparticles
December 16th 2024Photon upconversion converts low-energy photons to higher-energy photons. UCNPs, composed of rare-earth elements, can convert near-infrared light to visible or UV light. They have potential applications in solar energy and biomedicine. Understanding their luminescence properties is crucial for optimization. FS5 Spectrofluorometer was used for comprehensive upconversion characterization.
TA & Singlet Oxygen Phosphorescence of Rose Bengal
December 16th 2024Photosensitisers (PS) absorb light and reach a triplet excited state. This state interacts with a target species, transferring energy and inducing reactions. PS returns to its ground state and can participate in further photochemical activations.
Forensic Analysis of Paint Using Raman Microscopy
December 4th 2024Raman microscopy is a powerful technique for identifying the source of forensic samples, such as paint traces. As a non-destructive method of forensic analysis, evidence samples are not compromised during investigation. During forensic investigations, evidence samples are often compared to a database of known specimens for identification. In this Application Note, we show how the RM5 can be used to differentiate between different samples and how spectral library searching allows for the matching of paint samples within seconds.
