Method Performance Criteria Purpose Method for
the quantitative determination of melamine (and
cyanuric acid) in foodstuffs. The purpose of the
method is to provide food industry and
authorities with a method able to control
melamine adulteration and monitor low levels in
food. Applicability Milk, dairy products,
infant formula as well as food raw materials with
a high risk of economically driven
adulteration. Analytes melamine (cyanuric
acid) Limit of detection 0.05 mg/kg Regulatory
limits 1 mg/kg in milk-powder infant formula,
and 2.5 mg/kg in other foods Accuracy (method
recovery) 100 Selectivity (specificity)
Should be able to differentiate melamine from
cyanuric acid Repeatability (reproducibility) lt
15 Technology Mass spectrometry
