Identification of Color Additives in Powdered Drink Mix using Solid Phase Extraction and Automation of AOAC Method 988.13
14 Jun 2012In 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.

Solid-Phase ExtractionSolid-phase extraction (SPE) is used for clean-up, extraction and concentration of semi-volatile or non-volatile analytes from complex mixtures including blood, urine and food samples. Multiple formats are available for conducting SPE, including prepacked SPE cartridges, disks and microplates, as well as SPE sorbent powders for manual packing. SPE systems can be used to automate the process and extract multiple samples at once. Solid-phase microextraction (SPME) and supported liquid extraction (SLE) products are also available in the same formats.
