Full Description
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.
