Abstract
A two-dimensional liquid chromatographic analyzer, in which a temperature control part changes a temperature in a single-step manner and switches the temperature at a high speed. Also, the temperature control part has a holder around a separation column so that the temperature of the separation column can be changed to a preset temperature. A first separation column thereof changes elution time(s) of the objective component(s) by temperature modulation and the mobile phase of the first separation column is an aqueous mobile phase having a constant composition.
