  • USP正文Valproic Acid Capsules的含量测定中用到a high-speed blender,用它把胶囊打碎后测定含量。不知道这是个什么样的装置,在哪里能买到?
    原文如下:Assay preparation— Transfer not fewer than 20 Capsules to a blender jar or other container, add about 150 mL of methylene chloride, and cool in a solid carbon dioxide-acetone mixture until the contents have solidified. If necessary, transfer the mixture of Capsules and methylene chloride to a blender jar, and blend with a high-speed blender until all the solids are reduced to fine particles. Transfer the mixture to a 500-mL volumetric flask, add n-heptane to volume, mix, and allow solids to settle. Transfer an accurately measured volume of this solution, equivalent to 250 mg of valproic acid, to a 100-mL volumetric flask, dilute with n-heptane to volume, and mix. Transfer 5.0 mL to a container equipped with a closure. Add 2.0 mL of Internal standard solution, close the container, and mix.

    还有很多品种的含量测定中用到high-speed glass blender,USP中是否有这种装置的介绍呢?我们想用,可不知道在哪里能查到,望知道的给指导下呀。

    high speed blender应该和high speed mixer差不多的东西吧,一个是搅拌,一个是粉碎
