ABSTRACT:
A sample injector for a high-pressure liquid chromatography system that has an injector needle, which is freely movable within a three dimensional sample space. The needle is attached to a means of transport, which moves in the Y-, Y- and Z-axes. The needle can be moved to various sample intake positions on a sample tray and to the injection position where the sample is injected into the capillary system. The means of transport comprises a mechanism called X-carriage, which is movable in horizontal direction. The X-carriage has jib attached that performs the vertical movement. The jib a robot arm, which can rotate for .+-.180.degree. in a horizontal plane. The injection needle is attached to the end of the robot arm. The needle is connected with a metering means, through a flexible connection capillary comprising a glass capillary and a plastic coating. The combination of known high-pressure injection systems with a flexible capillary has the advantage that even the most minute sample can be injected in the analysis cycle without losses.
