Identification of Color Additives in Powdered Drink Mix using Solid Phase Extraction and Automation of AOAC Method 988.13

In this application, AOAC method 988.13 was automated using a Gilson GX-274 ASPEC™ to perform the SPE process just prior to automated spectrum analysis using the Agilent 8453 UV-visible Spectrophotometer with the Agilent 8-position Multicell Transport. FD&C Yellow No. 5, FD&C Red No. 40 and FD&C Blue No. 1 were extracted from various powdered drink mixes.
