This International Standard specifies a spectrometric method for the determination of the phosphorus content of animal feeding stuffs. The method is applicable to animal feeding stuffs with a phosphorus content less than 50 g/kg. It is particularly appropriate for the analysis of products with low phosphorus content. For products with higher phosphorus content, application of a gravimetric method is advised, using for instance quinoline phosphomolybdate.
Abstract
Overview
ISO 6491:1998 specifies a spectrometric method for the determination of phosphorus content in animal feeding stuffs. The method is intended primarily for feeds with low phosphorus content (below 50 g/kg) and describes sample preparation, chemical digestion routes, color development with a molybdovanadate reagent and spectrophotometric measurement. For very high phosphorus levels the standard recommends a gravimetric approach (for example, quinoline phosphomolybdate).
