Sampling flow cell with diamond window

DETAILED DESCRIPTION The embodiments of the invention in which an exclusive property of privilege is claimed are defined as follows: 1.
In material analysis cell of the type in which the material to be analyzed is passed continuously through a chamber in the cell, at high pressures and high temperatures, while being subjected to infrared radiation passed in a given direction through opposed windows in the wall of the cell, the improvement comprising: a tubular carrier member associated with each window, each tubular carrier member including an inner bore having an inner end of prescribed diameter adjacent the chamber and an outer periphery engaging the wall of the cell to retain the windows in the wall of the cell and juxtaposed with the chamber; the windows each being in the form of a diamond having a disk-like configuration including an outer periphery and a very thin wall thickness, in the direction of the infrared radiation, in relation to the overall diameter of the window, the diametric span of the disk-like configuration being only slightly grater than the diameter of the inner bore of the tubular carrier member at the inner end thereof; and each window being affixed adjacent the outer periphery thereof to the tubular carrier member such that the diamond is essentially integrated with the tubular carrier member with the diamond spanning the inner bore of the tubular carrier member at the inner end thereof.
2.
The invention of claim 1 wherein the difference between the diametric span of the disk-like configuration and the diameter of the inner bore of the tubular carrier member at the inner end thereof establishes a minimal affixation area along the outer periphery of the disk-like configuration, and each window is affixed adjacent the outer periphery thereof at the affixation area.
3.
The invention of claim 2 wherein the outer periphery of the disk-like configuration has a generally circular contour with a diameter only slightly greater than the diameter of the inner bore of the tubular carrier member at the inner end thereof
