A validated ICP-MS method for the determination of Cr, Se, and Mo in infant formula and adult nutritional products was transferred to a next-generation system. This methodology is potentially suitable as a global reference method for the application, as all samples can be analyzed using a single-cell gas mode (helium mode) that provides effective removal of polyatomic interferences - significantly improving productivity.
Real-Time Chemometric Analysis of Multicomponent Bioprocesses Using Raman Spectroscopy
In this study, a glycerol-fed, lab-scale E. coli bioprocess producing representative pharmaceutical compounds was monitored offline with a portable, high-sensitivity Raman spectrometer.
