Abstract
A high temperature sampling system is provided for obtaining a sample to be analyzed by liquid chromatography. A sample of a liquid to be analyzed, which is at an elevated temperature, is obtained by utilizing a plurality of valves to fill a sample conduit in a hot zone. The thus obtained sample is diluted and is then provided to a chromatographic analyzer sample valve which is located in a cooler zone. In this manner, samples of liquids are obtainable at temperatures substantially above those temperatures which can be withstood by a chromatographic analyzer sample valve.
