《GB/T 22388-2008原料乳与乳制品中三聚氰胺检测方法》由TC374（全国质量监管重点产品检验方法标准化技术委员会）归口，主管部门为国家标准化管理委员会。
本标准包括三个方法：第一法高效液相色谱法，第二法液相色谱-质谱/质谱法，第三法气相色谱-质谱联用法，检测时，应根据检测对象及其限量的规定，选用与其相适应的检测方法。本标准规定了原料乳、乳制品以及含乳制品中三聚氰胺的三种测定方法，即高效液相色谱法（HPLC）、液相色谱-质谱/质谱法（LC-MS/MS）和气相色谱-质谱联用法[包括气相色谱-质谱法（GC-MS），气相色谱-质谱/质谱法（GC-MS/MS）]。
本标准适用于原料乳、乳制品以及含乳制品中三聚氰胺的定量测定；液相色谱-质谱/质谱法、气相色谱-质谱（包括气相色谱-质谱/质谱）法同时适用于原料乳、乳制品以及含乳制品中三聚氰胺的定性确证。
本标准高效液相色谱法的定量限为2 mg/kg，液相色谱-质谱/质谱法的定量限为0.01 mg/kg，气相色谱-质谱法的定量限为0.05 mg/kg（其中气相色谱-质谱/质谱法的定量限为0.005 mg/kg）。

This standard specifies three determination methods for melamine in raw milk, dairy products and products containing milk, i.e. high-performance liquid chromatography (HPLC), liquid chromatography-mass spectrum/mass spectrography (LC-MS/MS) and gas chromatography-mass spectrum [including gas chromatography-mass spectrography (GC-MS), gas chromatography-mass spectrum/mass spectrography (GC-MS/MS)].
This standard is applicable to the quantitative determination of melamine in raw milk, dairy products and products containing milk; liquid chromatography-mass spectrum/mass spectrometry and gas chromatography-mass spectrum/mass spectrography (including gas chromatography-mass spectrum/mass spectrum) are simultaneously applicable to the qualitative corroboration of melamine in raw milk, dairy products and products containing milk.
The quantitation limit of high-performance liquid chromatography in this standard is 2 mg/kg; the quantitation limit of liquid chromatography-mass spectrum/mass spectrometry is 0.01 mg/kg; the quantitation limit of gas chromatography-mass spectrography is 0.05 mg/kg (among which the quantitation limit of gas chromatography-mass spectrum/mass spectrography is 0.005 mg/kg).
