摘要： A sample cell useful in fluorescent X-ray analytical devices is provided herein, which cell is composed of an inner frame; an inner frame cover and a radiation-permeable sheet which houses the sample to be analyzed and an outer frame which covers the sample. The inner frame cover which is formed by bending a soft plastic film and the radiation-permeable sheet are such that they may be discarded after each analysis whereas the inner frame and the outer frame are used for reinforcement and sealing up of the sample and are never contaminated with the sample to be analyzed. Since the inner frame cover and the X-ray permeable sheet are the only members of the sample cell which contact the sample to be analyzed, these portions have been made from inexpensive disposable materials so that they can be discarded after each X-ray analysis, thereby eliminating the need to wash the sample cell after each analysis. Since the inner frame and the outer frame are not in contact with the sample to be analyzed, these portions may be used repeatedly in conjunction with each new disposable inner frame cover and radiation-permeable sheet. According to the present invention, the troublesome and laborious cleaning operation necessary in conventional sample cells is eliminated and further, contamination of the hands or clothes by the sample to be analyzed is prevented.
摘要翻译：本发明提供了可用于荧光X射线分析装置的样品池，该单元由内框构成; 内部框架盖和容纳待分析样品的透射性片材和覆盖样品的外框架。通过弯曲软塑料膜和透射性辐射片而形成的内框架盖在每次分析之后可以被丢弃，而内框架和外框架用于加强和密封样品，并且永远不会被分析的样品污染。由于内框架盖和X射线透过片是与要分析的样品接触的样品池的唯一构件，所以这些部分由廉价的一次性材料制成，使得它们可以在每次X射线分析之后被丢弃，从而消除了在每次分析之后洗涤样品池的需要。由于内框架和外框架不与要分析的样品接触，所以这些部分可以与每个新的一次性内框架盖和可辐射透过的片材一起重复使用。根据本发明，消除了常规样品池中所需的麻烦和费力的清洁操作，并且防止了待分析样品对手或衣物的污染。
