Trace toxic and major nutrient elements were measured in a single measurement in a milk powder SRM, with no ionization buffers, using a synchronous dual view ICP-OES. The methodology was in accordance with Chinese method GB 5413.21 for raw milk and dairy products. Excellent recoveries were achieved for all elements determined in the SRM, demonstrating the accuracy of the method over a large dynamic range.
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.
