Five arsenic species, including the toxicologically relevant inorganic forms As(III) and As(V), were determined in 4 minutes, with excellent sensitivity, accuracy and precision using an Agilent LC fitted with a reversed phase column coupled to an ICP-MS. Any potential interferences on As such as ArCl+ were removed using a single-cell gas mode (helium mode), speeding up the analysis.
Reviewing the Impact of Raman Spectroscopy on Crop Quality Assessment: An Interview with Miri Park
February 1st 2024Miri Park of the Fraunhofer Institute for Environmental, Safety, and Energy Technologies is examining how Raman spectroscopy could aid non-destructive sensing in agricultural science. Recently, Park sat down with Spectroscopy to discuss micro-Raman spectroscopy's role in assessing crop quality, particularly secondary metabolites, across different contexts (in vitro, in vivo, and in situ), while suggesting future research for broader application possibilities.
Q&A: Portable FT-IR Empowers On-Site Food Quality Assurance
February 1st 2024Exploring the transformative capabilities of handheld Fourier transform infrared (FT-IR) spectrometers, Luis Rodriguez-Saona of The Ohio State University emphasizes their pivotal role in ensuring food integrity and safety across the entire supply chain.
