The suppressor consists of 3 suppression elements, which are used for inhibition in the circulation loop, which can be regenerated with sulfuric acid and rinsed with purified water, and regenerated outside the flow path can be analyzed to completely remove harmful substances. The use of micro-packed bed suppressor, its advantages are: smooth delivery of H+, low baseline noise, suitable for various concentration analysis, high pressure resistance, organic solvent resistance, heavy metal resistance, corrosion resistance, low noise, only.

The suppressor should avoid space-time rotation in unvented liquids. Blockage of the flow path of the eluent or regeneration solution and saturation of the suppressor will cause problems such as a sudden increase in system pressure and too high background conductivity. If, after a long period of time, the suppression element becomes contaminated and the normally used regeneration solution can no longer be completely removed, the baseline will rise significantly.

No, this will reduce his lifespan, and the material will become brittle, so it cannot be exposed to the sun, and must be placed in a cool place.

The reversible exchange between ions and the difference in the affinity of the analyte solute to the exchanger are separated. It is suitable for the separation of hydrophilic anions and cations.

For example, in the separation of several anions, after the sample solution is injected, the ion exchange is carried out directly with the ion exchange position of the analytical column (i.e., it is retained on the column), such as F-, Cl- and SO42- in the sample analyzed by NaOH as the eluent, the anions retained on the column are replaced by the OH- group in the eluent and eluted from the column. The analyte ions with weak affinity for resin are eluted before the analyte ions with strong affinity for resin, which is the ion chromatography separation process, in which the leachate passes through a chemical suppressor to minimize the background conductance from the eluent, so that when the analyte leaves the conductance cell, there is a large conductance signal that can be accurately measured.

Ion chromatography is mainly used for the analysis of environmental samples, including anions and cations in samples such as surface water, drinking water, rainwater, domestic sewage and industrial wastewater, acid precipitation and atmospheric particulate matter, and trace impurities in water and reagents related to the microelectronics industry.

In addition, it is also widely used in food, health, petrochemical, water and geology and other fields.

Common ions that are frequently detected are:

Anions: F-, Cl-, Br-, No2-, PO43-, No3-, SO42-, formic acid, acetic acid, oxalic acid, etc.

Cations: Li+, Na+, NH4+, K+, Ca2+, Mg2+, Cu2+, Zn2+, Fe2+, Fe3+, etc.

Ion chromatography is its specialty in separating and determining common anions, and a needle sample can be injected into it, and the results of 7 common ions can be obtained within about 20 minutes, which can not be achieved by other analytical methods, and the ion chromatography for the determination of cations does not show superiority compared with AAS and ICP methods.

Ion chromatography (IC) is one of the fastest-growing analytical methods in the field of analytical chemistry in recent years, which can determine various anions and cations, and the analysis of anions by ion chromatography is a new breakthrough in analytical chemistry. Ion chromatography is a type of high-performance liquid chromatography (HPLC) technique that separates and detects ionotypal, polar, and partially weakly polar compounds. The IC operation is simple and the sample analysis is reproducible; After dilution, filtration, a variety of samples can be measured, such as:

Multivalent oxidizable elements (NO2-, NO3-, SO32-, SO42-), etc.; The eluent system is simple and has little pollution to the environment; There are many detection methods of ion chromatography, including conductivity, electrochemical (amperometry), ultraviolet, fluorescence and other detectors; In addition, it has the advantages of high selectivity, sensitivity, rapidity, and simultaneous determination of multiple ions. Detection object and content: Ion chromatography technology has gradually developed into a multi-functional and multi-purpose aspect, from the analysis of common anions and cations to the analysis of a variety of complex organic molecules.

It can measure all kinds of anions and cations, especially in the determination of anions, and can analyze some alcohols, aldehydes, aromatic amines, amino acids, phenols, organic acids, sugars and proteins. Main application areas: energy, environment, food, medical and health, agriculture, hydrogeology, chemical metallurgy, semiconductor, electroplating, papermaking, textile and production quality control, etc.

It is for the measurement of anions.

On April 18, according to the Shandong Inspection and Quarantine Bureau, the project of "Development and Industrialization of Multifunctional Ion Chromatograph", a special project for the development of major national scientific instruments and equipment, passed the acceptance of the national technical expert group in Qingdao. The successful development of this project has filled the gap of China's high-end instrument products, and has important social and economic significance to break the monopoly position of similar foreign products in China's market.

This project was organized by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China, led by Qingdao Inspection and Quarantine Technology Development Center, and Qingdao Shenghan Chromatography Technology provided the first technical support, and was approved in December 2012. The project covers multifunctional R&D, hyphenated technologies, application methods, and engineering and industrial development of ion chromatographs. It has joined the research center of ecological environment of the Chinese Academy of Sciences, Zhejiang University, East China University of Science and Technology, Shandong Institute of Metrology, Beijing Physical and Chemical Analysis and Testing Center and many other units to participate.

Through the implementation of the project, 27 doctors, 74 masters and 1 overseas student have been attracted, and a total of 149 middle and high-end talents have participated in the research. In the process of project research and development, 20 doctors, 17 masters, 2 postdoctoral fellows and 3 senior visiting scholars have been trained. He has published 70 related articles, including more than 30 SCI articles, and applied for 42 patents.

The engineering prototypes of CIC-D160 and CIC-500 ion chromatographs were developed. 3 sets of process documents and 1 set of quality and reliability assurance plans have been compiled. Expanded 2 multi-functional ion chromatograph production lines with an annual output of 1,000 units.

The CIC-500 multifunctional ion chromatograph produced 6 prototypes and underwent performance tests. The CIC-D160 ion chromatograph, a phased product developed by the company, has been industrialized, and the ion chromatograph and some key components have been sold to 416 units across the country, including 163 sets of complete machines and 349 sets of key components, with sales of 24.85 million yuan. With the goal of developing the key technology of ion chromatography and establishing the actual needs of actual sample analysis, the successful transformation of scientific research achievements has been realized, and the technical barriers of foreign countries have been effectively broken through.

The research and development of the project has made breakthroughs and achieved innovation in some key technologies, such as the preparation of hydrophilic matrix nanoemulsions, hydrophilic modification of ST-DVB ion-pair chromatography packing materials with high cross-linking, resin-filled electrolytic self-regeneration inhibition, and bipolar pulse conductance technology. It has broken through the technology of high exchange capacity screen and flat film superposition, completed the structural design of eluent generator, and successfully broke the monopoly of foreign products.

Gas-liquid phase and ion chromatography can be put in one room, and it is best to place atomic absorption alone, because the solution of atomic absorption is acid, and the nitrogen oxides or sulfur oxides produced by combustion will become acidic after absorbing moisture, making the environment acidic, and it will corrode the mechanical parts of the instrument and cause damage after a long time.

Hello, glad to answer for you!

When the sample valve is switched to the injection position, the eluent substitutes the sample solution in the sample loop (or the ions eluted on the enriched and concentrated column) into the analytical column, and the anions on the side are separated according to their retention characteristics on the analytical column. When the eluent carries the sample through the suppressor, all cations are exchanged for hydrogen ions, the hydroxide type eluent is converted to water, and the carbonate eluent is converted to carbonic acid, and the background conductivity is reduced. At the same time, the measured anion is converted into the corresponding acid, the conductivity height. The response signal is detected by a conductivity detector and the ion chromatogram is recorded and displayed by the data processing system.

The measured ions are qualitatively measured by the retention time, and the anions are quantified by peak height or peak area, and the corresponding ion content is measured.

This method is particularly suitable for the determination of low concentrations of anions in aqueous solutions, such as drinking water quality analysis, ion analysis of high-purity water, mineral water, rainwater, various wastewater and power plant water, pulp and bleach, food analysis, ion determination in biological fluids (urine and blood, etc.), as well as applications in the steel industry, environmental protection, etc. Ion chromatography can determine the following types of ions: organic anions, alkali metals, alkaline earth metals, heavy metals, rare earth ions, and organic acids, as well as amines and ammonium salts.

Ion exchange equilibrium.

The stationary phase used in ion chromatography is ion exchange resins. Ion exchange resins are distributed with fixed and charged groups.

Coordination ions that swim. When the sample is added to ion exchange chromatography, if eluted with an appropriate solution, the sample ions are exchanged with the ions that can swim on the resin, and reversible exchange adsorption and desorption are carried out continuously to achieve adsorption equilibrium.

At present, ion chromatography has been widely used in energy, environment, metallurgy, electroplating, semiconductor, hydrogeology, etc., and has begun to enter the field of analysis related to life sciences. Since the introduction of ion chromatography in the early 80s, China has begun the application research of ion chromatography, and has also begun the development of instruments, which has been able to produce ion chromatographs. With the development of ion chromatography technology, the application of chromatographs in China will become increasingly popular.
