    • A high pressure liquid chromatography jacket includes a rectangular, fluid-tight enclosure which has a removable cover on which a pair of tubing seal fittings are mounted. The fittings form a fluid-tight seal around the inlet and discharge tubes of a chromatographic column which is mounted in the enclosure. The enclosure is connected to a source of temperature controlled fluid which circulates through the enclosure and controls the temperature of the chromatographic column.In an alternative embodiment of the invention, a valve is provided which allows sample materials being loaded to enter a sample storage loop, which is exposed to the temperature controlled fluid. The sample, whose temperature has been controlled by the temperature controlled fluid, is then injected into a chromatographic column under high pressure.
    • 高压液相色谱夹套包括矩形的流体密封外壳,其具有可移除的盖,一对管密封配件安装在其上。 配件在安装在外壳中的色谱柱的入口和放电管周围形成流体密封。 外壳连接到温度控制流体源,循环通过外壳并控制色谱柱的温度。 在本发明的替代实施例中,提供了一种阀,其允许加载样品材料进入暴露于受温度控制的流体的样品储存环路。 然后将其温度由温度控制的流体控制的样品在高压下注入色谱柱。

    • An all-TEFLON filter-degasser for removing solids and gases from a solvent. The filter-degasser has a filtering portion, a vacuum application portion downstream of the filtering portion, and a solvent bottle connecting portion. The vacuum application portion includes an externally tapered male member, and the solvent bottle connecting portion includes an internally identically tapered female member. The male member can be inserted into and withdrawn from the female member without requiring any relative rotation therebetween, so that the filter-degasser can be connected hermetically airtight to the solvent bottle likewise without any rotation being required therebetween. This abstract is not to be taken either as a complete exposition or as a limitation of the present invention, however, the full nature and extent of the invention being discernible only by reference to and from the entire disclosure.
    • 全TEFLON过滤器 - 脱气机,用于从溶剂中除去固体和气体。 过滤器脱气机具有过滤部分,过滤部分下游的真空施加部分和溶剂瓶连接部分。 真空施加部分包括外锥形凸构件,并且溶剂瓶连接部分包括内部相同锥形的阴构件。 阳构件可以插入阴构件中并从阴构件中取出,而不需要它们之间的任何相对旋转,使得过滤器脱气器可以气密地连接到溶剂瓶,同时不需要任何旋转。 该摘要不应被视为完全阐述或作为本发明的限制,然而,本发明的完整性质和范围仅在参考和从整个公开内容中可以看出。
