Abstract
An improved sample cell for use in a gas analyzer has a sample body with a measuring optical path extending traverse to the cell body. A sample gas inlet port is positioned at one end of the cell body, and a sample gas outlet port is positioned at the other end of the cell body. Porous plates can extend across the cell body, and appropriately-dimensioned apertures in the porous plates can ensure a consistent flow path of gas across the optical path without any stagnated flow patterns.
