Abstract:
To avoid "interference of a solution".
In this liquid chromatography unit of the present invention, an intermediate separation column is additionally connected between a preseparation column and a post separation column. A switching means and a liquid feed means for mixing a plurality of solutions to be fed are preferably added thereto to improve separation performance. The present invention provides the three-dimensional liquid chromatography unit for avoiding the "interference of the solution". A sample is thereby separation-analyzed simultaneously on line, even in the complicated sample mixed with a hydrophilic component and a hydrophobic component.
