Background

In order to improve the analysis precision and accuracy of stable isotopes of metals, a high-quality chemical purification process is a key for obtaining high-precision data. Most samples need to separate target metal elements by resin chromatography on the digested solution to remove matrix interference, and the separation and purification pretreatment process requires high recovery rate of the target elements and does not cause isotope fractionation of the target metal elements.

The resin column chromatography separation and purification method is widely used for the separation and purification pretreatment of metal elements for the purpose of metal stable isotope analysis. The resin separation method comprises filling ion exchange resin into a specific solid phase column, transferring multiple different solutions into the resin column by a liquid transfer device for resin activation and balancing treatment, adding a sample into the resin column, adding multiple different leaching solutions into the resin for eluting target metal elements, and collecting. The manual operation method has the following disadvantages: 1) Solution is removed and added, particularly, a small amount of solution is required to be added for many times, the labor intensity is high, and external pollutants are easily brought in during operation transfer; 2) The flow speed is slow under the action of natural gravity, so that the control is not easy when a plurality of columns are operated simultaneously, and the time consumption is long; 3) Strict operation is required for personnel, and the method is unfavorable for new-hand learning and method popularization. At present, prepcast-MC of ESI company in the United states can be used for automatic separation of metal elements, but is expensive, and the number of samples which can be processed is small because of the adoption of a syringe pushing liquid feeding mode. The domestic metal element resin separation device is provided with an automatic solid phase extraction device (utility model No. CN 111643928A), the gravity liquid inlet mode is adopted, the flow rate of the solution in the resin columns is still not controlled, the flow rates of different resin columns are different, the separation difference between the resin columns is further influenced, and the sample solution still needs to be manually added.
