Rapid Determination of Five Arsenic Species in Polished Rice Using HPLC-ICP-MS
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.
New Magnetic Flow Device Speeds Up Detection of Lactic Acid Bacteria and Yeast in Fermentation
November 11th 2024Researchers at Henan Agricultural University have developed a multi-channel magnetic flow device combined with surface-enhanced Raman spectroscopy (SERS) for the rapid and precise isolation, identification, and quantification of lactic acid bacteria and yeast, revolutionizing quality control in fermented food production.
