A high salinity wastewater treatment system is provided according to the present application, which includes a hydrogel loading system and a flow-storage different-oriented-inlet-and-outlet system. The hydrogel loading system includes six separation plates, a wastewater treatment area, a water distribution bin, a rotating shaft, a driving motor and a fixed bracket. The six separation plates evenly separate the wastewater treatment area into six separate treatment sectors in an axial direction. The six separate treatment sectors are filled with hydrogel materials with water purification effect. The high salinity wastewater infiltrates into each separate treatment sector one by one through high salinity wastewater inlet meshes on a surface of the wastewater treatment area, and the purified high salinity wastewater is discharged through a wastewater cleaning outlet pipe with a same water inlet direction as a cleaning filler distribution pipe.

An autosampler is switched selectively between an injecting mode where a sampling flow path is incorporated into an analysis flow path of a liquid chromatograph and a loading mode where the sampling flow path is not incorporated into the analysis flow path and injects a sample into the analysis flow path at a position farther upstream than a separation column by being switched to the injecting mode with the sample held in the sampling flow path, and includes a clog determiner configured to acquire a sending liquid pressure of a liquid sending pump that sends a mobile phase in the analysis flow path, obtain a variation value of the liquid sending pressure when the injecting mode and the loading mode are switched and determine presence or absence of a clog in a system incorporated into the analysis flow path in the injecting mode based on the obtained variation value.

A method and system for solid phase extraction of a compound of interest from a sample matrix using a syringe having a barrel and a plunger, a sorbent for use with the syringe, and a desalting purification column having an end configured to receive liquid from the syringe body.

A process for transferring a method from a starting system to a target system in liquid chromatography, in particular in high performance liquid chromatography, is described. A first chromatogram of the method carried out on the starting system is available or determined. The method developed for the starting system is carried out on the target system without any change in its physical parameters, and a second chromatogram is thereby determined. The two chromatograms of the starting system and the target system are compared, and measures for adjusting the physical system parameters of the target system are derived from the deviations.
