Qingdao Puren Instruments PIC series ion chromatograph is widely used in pure water, drinking water, ecological environment protection, modern agriculture, quality inspection, disease control center, petroleum industry, fine chemical industry, colleges and universities, scientific research, testing institutions and other systems. The purpose of this article is to share: Ion chromatography instruments can be used to determine anions and cations in chloroform and ionic liquids.

Chloroform, colorless and transparent liquid, has special odor, sweet taste, high refractive index, non-flammable, heavy and easily volatile. The pure product is more sensitive to light. When exposed to light, it will react with oxygen in the air and gradually decompose to form highly toxic phosgene (carbonyl chloride) and hydrogen chloride. 0.6%~1% ethanol can be added as a stabilizer. Chloroform is a chemically synthesized raw material, mainly used to produce Freon (F-21, F-22, F-23), organic dyes and pharmaceuticals. In clinical medicine, it is often used as a local anesthetic. It can be used as an organic solvent and extractant for antibiotics, spices, oils, resins, and rubber. It can be mixed with carbon tetrachloride to make a non-freezing fireproof liquid. It is also used as a propellant for aerosols, a fumigant for grains and a standard solution for temperature calibration.

Ion chromatography instrument can be used for the determination of anions and cations in ionic liquids

Ionic liquid, also known as room temperature ionic liquid or room temperature molten salt, refers to a molten salt that exhibits a liquid state at or near normal temperature, usually composed of specific organic cations and inorganic anions (or organic anions). It not only has the advantages of traditional organic solvents, but also shows many unique physical and chemical properties compared with organic solvents, and has excellent properties such as odorless, green environmental protection, non-flammable, easy to separate from products, easy to recycle, and can be recycled repeatedly. It can effectively avoid serious environmental and health problems caused by the use of traditional organic solvents. More importantly, the physical and chemical properties of ionic liquids can be changed by changing the species of cations and anions. Therefore, ionic liquids have become a kind of artificially designed "green solutions", showing great industrial application prospects, and are widely used in chemical synthesis, electrochemistry and other industries.
