ANALYSIS OF LIQUID STREAMS USING TUBING WITH PROTUBERANCES ON ITS INNER WALL

摘要

The constituents of a liquid stream are analyzed by flowing the stream through a hollow tube or fiber with spaced protuberances of a character to disrupt laminar flow and to produce turbulence. In one embodiment, the tubing includes ion exchange sites and is preferentially permeable to one of the ions of an electrolyte. In this manner, the tubing is useful as an electrolyte suppressor in ion chromatography in which the analyte ions are separated by chromatography using the electrolyte and the electrolyte is converted to weakly ionized form by passage through the tubing prior to conductivity detection.
