对照品实验方法与判定:
1.对照品溶液的稳定性
2.对照品溶液的配制:精密量取脑对照品适量,加无水乙醇制成每1ml含脑1mg的溶液,作为对照品溶液。
3.色谱条件:以交联键合聚乙二醇为固定相的毛细管柱;柱温120℃;进样口温度250℃;检测器温度250℃;分流进样,分流比10:1。理论塔板数按脑计算应不低于10000。
4.实验方法:配制的对照品溶液,一份置冷处保存,一份置室温中保存,在第1、3、7、10、15天重新配制一份对照品溶液,三种储备液同时稀释制成每1ml中约含50ug的溶液。照气相色谱法,并依据新对照品的峰面积计算原对照品溶液的含量。记录下来,保证原对照品溶液含量在考察期相对平均偏差不超过2.0%,验证对照品溶液在使用期内稳定可靠。

标准品和对照品的区别:
☆对照品:用于鉴别、检查、含量测定和校正检定仪器性能的标准物质。对照品系指用于生物制品理化等方面测定的特定物质,由生产单位采用与制品生产工艺相同的方法制备。对照品应尽可能与制品原液配方一致,稳定性较差的,可加不含对测定有干扰物质的适宜的稳定剂。对照品由国家药品检定机构审查认可,其标准应不低于制品的质量标准。
☆标准品:用于生物检定、抗生素或生物药品中含量或效价测定的标准物质,以效价单位(U)表示。国家标准品及生物参考品系指用于鉴别、检查含量或效价测定的标准物质,其制备与标定应符合“生物制品国家标准物质制备和标定规程”要求,并由药品监督管理部门指定的机构分发。企业工作标准品或参考品必须经国家标准品或参考品标化后方能使用。
