ABSTRACT:
A detection unit having a solute detector and a transport system with a quartz fiber conveyor is disclosed that is particularly useful for liquid chromatography. The quartz fiber conveyor is a porous belt that is mounted at the periphery of a rotatable disc so that the total effluent to be detected is applied to the belt as it is rotated within a heated housing enclosing the disc. The volatile solvent of the effluent is removed by evaporation within the heated housing to leave the non-volatile organic solute on the quartz fiber conveyor, which solute is then detected by a solute detector such as a flame ionization detector or a stacked flame photometric detector. After detection, the quartz fiber conveyor is cleaned by hydrogen-oxygen flame and is thus made ready for further transport of effluent. Alternate embodiments of a stacked flame photometric detector and top flame jets connected therewith are disclosed, as is a device to fabricate the quartz fiber conveyor.
