The application discloses a blood separation device, which is suitable for synchronous centrifugal motion with a centrifugal driving device, and comprises a sample bin, a flow guide pipe, a sensing assembly, a valve assembly, a distribution bin and a controller. The sample bin is communicated with the inlet end of the valve assembly through the flow guide pipe. The valve assembly can be switched among three states of closing the inlet end, communicating the inlet end with the first outlet end and communicating the inlet end with the second outlet end. The distribution bin is provided with independent storage cavities communicated with the two outlet ends respectively. The controller controls the valve state switching according to the detection signal of the sensing assembly. The blood component export and component separation are completed by centrifugal force driving. The device can complete component separation without stopping centrifugation, and the pump body and rotary sealing joint are omitted, so that the structure is simplified. The secondary mixing of blood components caused by stopping is avoided, and the separation efficiency and purity are improved. The whole process is automatically operated, and the manual operation and pollution risk are reduced.

This invention relates to a chip separation device for CNC machine tools and the CNC machine tool itself. The separation device includes a frame, a guide channel mounted on the frame, multiple magnetic suction components, a filter component, and a recovery device. The guide channel is inclined to convey a mixture of chips and coolant collected by the machine tool to the filter component. Multiple magnetic suction components are spaced apart along the extension direction of the guide channel. Each magnetic suction component can move independently into the guide channel to magnetically attract the chips in the mixture and can be removed from the guide channel to release the magnetic attraction. The filter component filters out the coolant from the mixture output from the guide channel and separately conveys the coolant and the filtered chips to the recovery device for recycling. This invention removes chips more thoroughly and efficiently. Furthermore, by initially separating the chips with magnetic suction components and then filtering them with the filter component, the processing load on the filter component is reduced, the equipment size is reduced, and the equipment is more conducive to miniaturization.

The application belongs to the technical field of chiral chromatographic separation, and discloses a chiral chromatographic separation and analysis method for homosalate enantiomers. The chiral chromatographic separation and analysis method is used for the first time for homosalate enantiomers, and the chiral chromatographic separation and analysis method selects a mixed solution composed of n-hexane and MTBE (methyl tert-butyl ether) as a mobile phase, and successfully realizes chiral separation of four enantiomers of homosalate on a polysaccharide derivative chiral stationary phase (bonded type straight-chain amylose-tris (3-chloro-5-methyl phenyl urea)). The chiral chromatographic separation and analysis method has high resolution, is simple and easy to operate and control, has low detection cost, and has good stability.
