Abstract

The heparin column solid-phase extraction device comprises a main body support and a ventilation pipeline, the main body support comprises a base with a hollow column, and a centrifugal tube supporting plate, a centrifugal tube positioning plate, a heparin column positioning plate and an injector cylinder mounting plate are sequentially arranged on the outer diameter of the hollow column of the base with the hollow column from bottom to top; a waste liquid disc is arranged on the base with the hollow column and located on the lower side of the centrifugal tube supporting plate, and a panel installation internal thread connector is arranged on the injector barrel installation plate and located on the upper side of the hollow column. By means of air pressure and the plug cover, pressure is stably applied to sample loading liquid, manual column passing extrusion during column passing is relieved, and column passing pressure is stabilized at the same time; different column passing pressure requirements are controlled through the valve of the four-channel combination valve, so that the sample column passing rates are similar, and the influence of different rates on the recovery rate is reduced; and a plurality of syringe barrels can be simultaneously subjected to one-time sample loading, so that the trouble of repeated sample loading is reduced, and the efficiency is improved.

Description

technical field [0001] The present invention relates to the field of solid-phase extraction of liquid samples, in particular to a heparin column solid-phase extraction device and a method thereof. Background technique [0002] Solid-phase extraction is a sample pretreatment technology developed in recent years. It is developed from the combination of liquid-solid extraction column and liquid chromatography technology. It is mainly used for the separation, purification and concentration of samples. It is similar to the traditional liquid-liquid extraction method. Comparisons can improve analyte recovery and more efficiently separate analytes from interfering components. Heparin column solid phase extraction is one of them, which has a significant effect on the analysis of milk components, but it is difficult to filter samples, the efficiency is slow, and the speed of column passing affects the recovery rate. SUMMARY OF THE INVENTION [0003] The purpose of the present inve...
