ISO 9874|IDF 42:2006 specifies a molecular absorption spectrometric method for the determination of the total phosphorus content of milk.
Abstract
ISO 9874:2006 (IDF 42:2006) - Milk - Determination of total phosphorus content
Overview
ISO 9874:2006 specifies a validated laboratory method for determining the content of milk using . The method converts phosphorus into a coloured molybdenum‑blue complex and measures absorbance at . It covers sample preparation (wet digestion or dry ashing), reagent and apparatus requirements, calibration, calculation, precision and reporting. This standard is published jointly by ISO and the International Dairy Federation (IDF 42).
