专利汇可以提供Dual beam optical absorption photometry detector assembly for high pressure applications专利检索,专利查询,专利分析的服务。并且A detector assembly providing a sample cell and a reference cell for use in a dual beam optical absorption photometry instrument wherein the reference cell and sample cell are formed by a pair of bores extending through a main detector body in an axial direction from one end of the body to the other end, each end of the body being provided with apparatus to seal the reference and sample bores from each other comprising a transparent lens with a flat surface positioned at the end of the body and over the cell openings, the outer face of the lens being convex, a thin sheet gasket material overlying the outer face of the lens, a metal pressure plate overlying the gasket material, both the gasket and pressure plate being provided with openings therein aligned with the sample and reference bores in the cell body, and means for exerting a pressure on the surface of the pressure plate whereby the pressure plate exerts a force on the gasket and lens to force the lens against the end wall of the cell body, the pressure plate deforming under pressure to assume the convex shape of the outer face of the lens whereby the pressure applied by the pressure plate is spread over the surface area of the lens with a maximum pressure applied at the central region thereof which is aligned with the wall section of the main body between the two cell bores. In one embodiment, an additional gasket material is positioned between the flat surface of the lens and the end of the cell body with suitable openings therein aligned with the sample and reference cell bores, this additional gasket material either being heat treated to fuse to the cell body and lens face and provide additional sealing or left in its natural state to provide resilience at the surface of the seal.,下面是Dual beam optical absorption photometry detector assembly for high pressure applications专利的具体信息内容。
