ISO 20638:2015 specifies a method for the quantitative determination of 5′-mononucleotides in infant formula in solid (i.e. powders) or liquid (i.e. ready-to-feed liquids and liquid concentrates) forms using liquid chromatography.
Abstract
Overview
ISO 20638:2015 defines a validated analytical method for the quantitative determination of in (powders, ready-to-feed liquids, and liquid concentrates) using . The standard specifies sample preparation, solid-phase extraction (SPE), chromatographic separation on a C18 stationary phase, UV detection with a photodiode array detector, and quantitation using an internal standard (thymidine 5′-monophosphate, ). The method is equivalent to AOAC Official Method 2011.20 and was developed by ISO/TC 34 (Food products).
