Scope

This Standard specifies three determination methods for melamine in raw milk,
dairy product as well as products containing dairy, i.e., high performance liquid
chromatography (HPLC), liquid chromatography - mass spectrometry/mass
spectrometry (LC-MS/MS) and gas chromatography - mass spectrometry
[including gas chromatography-mass spectrometry (GC-MS), gas
chromatography - mass spectrometry/mass spectrometry (GC-MS/MS).
This Standard applies to the quantitative determination of melamine in raw milk,
dairy products and products containing dairy. Liquid chromatography - mass
spectrometry/mass spectrometry and gas chromatography - mass
spectrometry (including gas chromatography - mass spectrometry/mass
spectrometry) are applicable simultaneously to the qualitative confirmation of
melamine in raw milk, dairy products, and products containing dairy.
The limit of quantitation of HPLC of this Standard is 2 mg/kg. The limit of
quantitation of liquid chromatography - mass spectrometry/mass spectrometry
is 0.01 mg/kg. The limit of quantitation of gas chromatography - mass
spectrometry is 0.05 mg/kg (the limit of quantitation of gas chromatography -
mass spectrometry/mass spectrometry is 0.005 mg/kg).

Summary	This standard specifies the raw milk, dairy products and three measurement methods for containing melamine in dairy products. That performance liquid chromatography, liquid chromatography-mass spectrometry/mass spectrometry and gas chromatography-mass spectrometry. This standard applies to raw milk, dairy products and dairy products containing melamine quantitative determination, liquid chromatography-mass spectrometry/mass spectrometry, gas chromatography-mass spectrometry applied to both raw milk, dairy products and dairy products containing melamine qualitative confirmed. This standard HPLC quantitation limit of 2 mg/kg, liquid chromatography-mass spectrometry/mass spectrometry quantification limit of 0. 01 mg/kg, gas chromatography-mass spectrometry quantification limit of 0. 05 mg/kg.
