Detecting apparatus for liquid chromatography

摘要

An improved detection apparatus employable in liquid chromatography for analyzing a selected non-volatile phase of a liquid effluent is described. A vibrating capillary tube is coupled to the effluent source for atomizing the effluent. The atomizer communicates with a first end of a heated separation column, which is in further communication with a carrier gas source. The non-selected components of the effluent are volatilized in the separation column, while the non-volatilized phase is propelled by means of the carrier gas out of the separation column and through a suitable sensor via a control valve such as a diaphragm. The sensed selected phase is thereupon recorded and analyzed in a conventional manner.
