《GB/T 14609-2008粮油检验 谷物及其制品中铜、铁、锰、锌、钙、镁的测定 火焰原子吸收光谱法》由TC270(全国粮油标准化技术委员会)归口,TC270SC1(全国粮油标准化技术委员会原粮及制品分会)执行,主管部门为国家粮食和物资储备局。
本标准代替GB/T 14609-1993 《谷物中铜、铁、锰、锌、钙、镁的测定法 原子吸收法》。
本标准规定了用火焰原子吸收光谱法测定谷物及其制品中铜、铁、锰、锌、钙、镁的原理、试剂、仪器与设备、分析步骤、结果计算和重复性。
本标准适用于谷物及其制品中铜、铁、锰、锌、钙、镁等元素的测定。
本方法检出限:铜为0.6mg/kg,铁为2.4mg/kg,锰为0.5mg/kg,锌为0.4mg/kg,钙为1.5mg/kg,镁为0.7mg/kg。
本标准与GB/T 14609-1993 相比,主要技术差异如下:
―――修改了标准的中文名称,改为《粮油检验 谷物及其制品中铜、铁、锰、锌、钙、镁的测定 火焰
原子吸收光谱法》;
―――增加了方法检出限;
―――增加了湿式消解和微波消解两种样品前处理方法。
Scope
