Abstract
The present invention discloses a circulating multidimensional liquid chromatography and application thereof. The liquid chromatography comprises an infusion device, a sampling device, a collecting-resampling device, a chromatographic column switching device and a detecting device which are connected sequentially, wherein the collecting-resampling device comprises a collecting valve and a sample ring, and the collecting valve is connected with the sample ring; the sampling device is successively connected with the collecting valve and the chromatographic column switching device; the detecting device is also connected with the collecting valve; and the collecting valve is a three-slot three-position multi-way valve. The present invention adopts the three-slot three-position multi-way valve as the collecting valve, and the creative rotor flow path design can simultaneously satisfy the requirements of collection and resampling of the circulating multidimensional liquid chromatography, and greatly simplifies the hardware configuration.
