Abstract
A spectroscopic fluid sample apparatus for the transmission and detection of radiation with the key components being a housing; a helical bore formed by the housing and extending through the housing for conducting the sample fluid through the bore to induce centripetal acceleration on the sample fluid and establish a radial composition gradient across the sample fluid in the bore; a fluid inlet and a fluid outlet each in fluid communication with the helical bore; and a spectroscopic sample interface in fluid communication with the fluid outlet has been developed.
