DESCRIPTION
BS ISO 23970:2021
This standard BS ISO 23970:2021 Milk, milk products and infant formula. Determination of melamine and cyanuric acid by liquid chromatography and tandem mass spectrometry (LC-MS/MS) is classified in these ICS categories:
- 67.100.10 Milk and processed milk products
This document specifies a method for the determination of melamine and cyanuric acid with liquid chromatography in combination with tandem mass spectrometry (LC-MS/MS). The method has been validated in an interlaboratory study via the analysis of spiked samples of milk-based infant formula, soy-based infant formula, milk powder, whole milk, soy drink and milk chocolate ranging from 0,71 mg/kg to 1,43 mg/kg for melamine and 0,57 mg/kg to 1,45 mg/kg for cyanuric acid. The limits of quantification (LOQ) for melamine and cyanuric acid in food are 0,05 mg/kg and 0,25 mg/kg, respectively. The upper limit of the working range is up to 10 mg/kg for melamine and up to 25 mg/kg for cyanuric acid.
