SPECTRAL TRANSMISSION FOR COLOURED GLASS CONTAINERS
有色玻璃容器的光透射试验
Equipment. A UV-VIS spectrophotometer, equipped with a photodiode detector or equipped with a photomultiplier tube coupled with an integrating sphere.
紫外-可见分光光度计，配备有一个光电二极管检测器，或者配备有一个带有累计球的双光束光电倍增管。
Preparation of the specimen. Break the glass container or cut it with a circular saw fitted with a wet abrasive wheel, such as a carborundum or a bonded-diamond wheel. Select sections representative of the wall thickness and trim them as suitable for mounting in a spectrophotometer. If the specimen is too small to cover the opening in the specimen holder, mask the uncovered portion with opaque paper or tape, provided that the length of the specimen is greater than that of the slit. Before placing in the holder, wash, dry and wipe the specimen with lens tissue. Mount the specimen with the aid of wax, or by other convenient means, taking care to avoid leaving fingerprints or other marks.
样品制备
将玻璃瓶压碎，选取其中壁厚的有代表性的一部分，适当修剪以便于安装在分光光度计上。如果所取样品过小不能覆盖样品台上的开孔，用不透明的纸或胶带将没有覆盖的部分遮住，所提供的样品长度应该大于狭缝的长度。将样品放入样品架之前，应先将样品洗净，干燥，并用镜头纸擦拭干净。将样品放在样品架上，用蜡或其它合适的方式封好，但要小心，以防止留下指纹或其它的痕迹。
Method. Place the specimen in the spectrophotometer with its cylindrical axis parallel to the slit and in such a way that the light beam is perpendicular to the surface of the section and that the losses due to reflection are at a minimum. Measure the transmission of the specimen with reference to air in the spectral region of 290-450 nm, continuously or at intervals of 20 nm.
测试方法
将样品放入分光光度计，使其圆柱轴与狭缝平行，这种方式可以使光垂直照射在样品的表面上并使光反射的损失最小。在290nm-450nm范围内的任一波长处，以空气为参照，测定样品的透光率。
Limits. The observed spectral transmission for coloured glass containers for preparations that are not for parenteral use does not exceed 10 per cent at any wavelength in the range of 290 nm to 450 nm, irrespective of the type and the capacity of the glass container.
限度：对于非肠道使用的制剂，不论有色玻璃容器的大小及类型，在290nm-450nm范围内的任一波长处，其透光率均应不超过10%。

没做过这方面的测试，现在需要先制订SOP，但感觉翻译的很生硬，可操作性不强，麻烦指点。
