Abstract
A spectroscopic fluid sample cell for the transmission and detection of radiation with the key components being a housing; a centripetal acceleration chamber formed by the housing and extending through the housing for circulating a fluid through the housing over a curvilinear flow path about a rotational axis; a pair of windows aligned along a common axis intersecting a portion of the chamber and parallel to the rotational axis; a fluid inlet and a fluid outlet in communication with the centripetal acceleration chamber; and a flow director positioned in the housing to induce centripetal acceleration on fluid passing through the chamber and establish a radial composition gradient across the fluid chamber has been developed.
