A simple system is described for the introduction of gases into standard X-ray diffraction capillaries mounted in situ in the X-ray beam of laboratory X-ray diffraction instruments. This system retains many of the advantages of the standard Norby cell, but does not require custom machining and has less stringent space restrictions. The system has been used to study the crystallization and interaction of volatile organics at cryogenic temperatures, but gas–solid interactions could also be studied at elevated temperatures using this approach.

一种用于低温粉末 X 射线衍射的简单气体引入系统

描述了一个简单的系统，用于将气体引入原位安装在实验室 X 射线衍射仪器的 X 射线束中的标准 X 射线衍射毛细管中。该系统保留了标准 Norby 单元的许多优点，但不需要定制加工，空间限制也不那么严格。该系统已被用于研究低温下挥发性有机物的结晶和相互作用，但也可以使用这种方法在升高的温度下研究气固相互作用。
