Anions and cations standards are a kind of standard substance with high purity, which is mainly used in ion chromatography analysis. Ion chromatography can realize the qualitative and quantitative analysis of anions and cations. In quantitative analysis, the concentration of detected ions is directly proportional to the peak area or peak height, so the peak area or peak height is taken as the quantitative basis for quantitative analysis through the standard curves. Anions and cations standards are required when making standard curves. Common anions and cations standards include butyrate standard, fructose standard, ammonium standard, cyanide standard, bromide standard, calcium standard, magnesium standard and others.
Anions and cations standards can be applied to the detection of inorganic anions and cations as well as organic anions and cations.
Detection of inorganic anions and cations: It is the earliest and most mature ion chromatography method to use anions and cations standards for quantitative analysis of inorganic anions and cations. For example, halogen anions of aqueous samples such as fluorine, chlorine, bromine, sulfate, thiosulfate, cyanogen and others can be quantitatively detected through anions and cations standards, which is widely used in the detection of drinking water quality, beer, beverage and other food safety. In addition, anions and cations standards may also be applied to the quality control of industrial products such as wastewater discharge standards detection, metallurgical process water samples, and petroleum industry samples. In particular, with the rapid development of the electronic industry, the residue of halogen ions in the electronic industry is more and more strictly limited, anions and cations standards can be well used for quantitative detection.
Detection of organic anion and cation: It is a new development direction in recent years to use anions and cations standards to detect organic anions and cations, which can be used to analyze certain complex ions in biological samples. For example, based on anions and cations standards, quantitative analysis of components such as putrescine, histamines, cadaverine and others can be realized, which has become an important detection means in criminal detection systems and forensic medicine. In addition, anions and cations standards can be applied to effectively analyze various organic acids, including lactic acid, formic acid, acetic acid, propionic acid, butyric acid, valproic acid, isopentyl acid, isopentyl acid, malic acid, citric acid and others. It is a simple and effective separation method in microbial fermentation industry and food industry. Furthermore, many sugars such as glucose, lactose, arabinose, sucrose and others can also be analyzed using anions and cations standards, which are especially widely used in the food industry.
