The conventional infrared absorption cell utilizes two amalgamated lead gaskets. One of these gaskets is placed between two salt plate windows and serves as the cell spacer (i.e., determines the light path length of the cell). The other amalgamated lead gasket serves as a true gasket, providing a seal between the cell body and the upper salt plate. The cell normally is filled by passing the sample through a hypodermic hub, through a hole in the cell plate, through an opening in the amalgamated lead gasket, then through holes drilled in the upper salt plate, and finally the space between the two salt plates. When materials that tend to "mess" up the cell are used, it is necessary to frequently disassemble the cell for cleaning. The preparation of amalgamated lead gaskets is quite time consuming and in most instances does not give a leak-proof cell.
