Abstract
Liquid chromatography systems described herein are smaller in size and with a reduced extra-column volume due to direct connection of a liquid chromatography column and/or detector to an injector valve and due to eliminating the need for a column oven by relying on heating of the liquid chromatography column and detector by a preheater. The size of the liquid chromatography systems are enough that the liquid chromatography systems may be deployed adjacent to automated sample preparation robotics, adjacent to a process stream, or adjacent to the inlet of a mass spectrometer. In addition, the extra-column volume of the liquid chromatography systems may be reduced by eliminating many of the connection tubes and by situating components of the liquid chromatography system in closer proximity.
