Embodiment Construction

[0023] The present invention utilizes Dionex ICS-2000 ion chromatograph, Dionex ICS-900 ion chromatograph and self-made anion exchange chromatographic column to realize the simultaneous detection of iodide ion and iodate ion, wherein Dionex ICS-900 ion chromatograph only uses its advanced sample valve. The low-exchange-capacity chromatographic column and the high-exchange-capacity chromatographic column are connected in sequence to the six-port valve of the Dionex ICS-2000 ion chromatograph. Before the valve is switched, the flow path of the system is eluent generator 8, quantitative loop, low exchange capacity chromatographic column 4, high exchange capacity chromatographic column 5, suppressor 3 and conductivity detector 2; after the valve is switched, the system flow The road is sequentially the eluent generator 8, the quantitative loop, the high exchange capacity chromatographic column 5, the low exchange capacity chromatographic column 4, the suppressor 3 and the conducti...

Abstract

The invention relates to a use system for instrumental analysis, in particular to an ion chromatography-valve switching analysis system for simultaneously detecting iodide ions and iodate ions. The ion chromatography-valve switching analysis system is provided with an anion exchange chromatographic column comprising a chromatographic column with low exchange capacity and a chromatographic column with high exchange capacity, wherein the chromatographic column with the low exchange capacity retains the iodide ions to a certain degree while hardly retaining some weak retention ions including the iodate ions, and the chromatographic column with the high exchange capacity is capable of effectively separating various weak retention ions. The iodide ions can be rapidly eluted only through the chromatographic column with the low exchange capacity, by means of simple valve switching, the weak retention ions including the iodate ions and the like can be effectively separated, analysis time is shortened, and analysis efficiency is improved.

Description

technical field [0001] The invention relates to a chemical instrument analysis application system, in particular to an ion chromatography-valve switching analysis system involving simultaneous detection of iodide ions and iodate ions. Background technique [0002] As a modern analytical method, ion chromatography is widely used in the detection of various ionic compounds. Complex samples contain various ions, which usually require a long analysis time, but sometimes our target ions are only a few of them, and it is not necessary to detect all ions in the sample. The ion chromatography-valve switching technology can select the target ion for detection, which solves this problem better. Iodine is an essential trace element for the human body (including all animals). It mainly exists in nature in the form of iodide ion and iodate ion. The lack of iodine element will lead to various diseases, such as thyroid hypertrophy, hypothyroidism, mental retardation, etc. , especially th...
