Abstract

The invention discloses an adjustable fully-automatic ion exchange column. The adjustable fully-automatic ion exchange column comprises a K-type fixed clamping plate, a fixed rod, an adjustable tightening inner screw rod, a positioning pin, an ion column, a light emitting diode (LED), a photosensitive diode, a connector, a flow pipe, a hollow screw, a two-way micro electromagnetic valve, a signalprocessing end and a power supply switch. The ion column is fixed between K-type fixed plate and the fixed rod by virtue of the adjustable tightening inner screw rod and the positioning pin; the LED and the photosensitive diode are respectively installed right on the centers of the K-tyep fixed clamping plate and the fixed rod, a photoelectric signal is changed by virtue of the rising and fallingof the liquid surface, and the signal is transmitted to the signal processor; and the upper end and the lower end of the two-way micro electromagnetic valve are respectively connected with the flow pipe by virtue of the hollow screw, and the power supply switch is controlled by virtue of the signal processing end, so that the fully-automatic control for a flow path can be realized. The adjustablefully-automatic ion exchange column is simple in operation, capable of precisely automatically controlling the liquid surface and avoiding the dryness of resin, high in chemical separation concentration enrichment reproducibilityrepetition, automatically-switchable, and capable of saving the manpower.

Description

technical field [0001] The invention relates to the field of ion exchange column design in analysis and testing, in particular to an adjustable fully automatic ion exchange column. Background technique [0002] In analytical chemistry experiments, it often involves the detection of trace elements or the detection of trace elements in a variety of interfering matrices. Especially in isotope analysis, it is necessary to separate the interfering elements, so before analyzing and testing the target elements, it is necessary to The samples were pretreated to achieve the purpose of eliminating matrix element interference and improving detection sensitivity. [0003] Ion exchange is often used as a method of sample pretreatment. Generally, a selective ion exchange resin is selected as the ion exchanger. The ion exchange process is a reversible chemical reaction between ions in the liquid phase and ions in the solid phase. , when some ions in the liquid phase are more preferred by ...
