Embodiment Construction

[0012] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0013] Such as figure 1 The fully automatic element separation and purification device shown includes a syringe pump 1, a first multi-channel switching valve 2, a second multi-channel switching valve 3, a two-position six-way valve 4, an ion chromatography column 5, and a collector 6. The syringe pump 1 is connected to the common port of the first multi-channel switching valve 2 with a tube not smaller than 1 / 8 inch, and the remaining ports of the first multi-channel switching valve 2 are respectively connected to the pure water tank 7, the eluent tank 8, and the concentrated acid tank. 9. The air tank 10 and the No. 5 port of the two-position six-way valve 4 are connected. The No. 1 port and No. 4 port of the two-position six-way valve 4 are connected by the sample loop 13, and the sample loop is not 1 / 8-inch tube less than 5cm, the No. 2 ...

Abstract

The invention discloses a full-automatic element separating and purifying device which comprises an injection pump, a first multichannel switch valve, a two-site six-way valve, a second multichannel switch valve, an ionic chromatographic column and a collector, wherein the injection pump is connected with a public opening of the first multichannel switch valve, and the rest connectors of the firstmultichannel switch valve are respectively connected with a pure water tank, a leacheate tank, a concentrated acid tank, an air tank and a fifth opening of the two-site six-way valve; a first openingand a fourth opening of the two-site six-way valve are communicated through a sample feeding ring, a second opening of the two-site six-way valve is used for receiving a sample, a third opening of the two-site six-way valve is used for discharging a redundant sample in the sample feeding ring, a sixth opening of the two-site six-way valve is communicated with an inlet of the ionic chromatographiccolumn through a pipeline, and an outlet of the ionic chromatographic column is communicated with the collector through the second multichannel switch valve. The device solves the technical defect ofthe low efficiency of an existing element separating and purifying device, can automatically operate, avoids time-consuming manual operation and can effectively prevent related safety accidents caused by corrosive chemical reagents.

Description

technical field [0001] The invention relates to a fully automatic element separation and purification device. Background technique [0002] Element separation and purification is a commonly used experimental method in analytical chemistry testing. It can effectively enrich the target elements in the purification system and eliminate the interference of a large number of elements and isobaric elements on element content and isotope testing. It is widely used in earth sciences, medicine, and materials. fields of science. The current separation and purification of elements mostly adopts the ion exchange method, which uses manual operation. During the experiment, the experimenter needs to manually operate for a long time, and only one or a few samples can be purified at the same time, which is heavy workload and low efficiency. The eluent flows down the chromatography column by gravity, and it is difficult to control the flow rate, which needs to be monitored by the experimente...
