Common analytes analyzed by ion chromatography
Ammonia is a hazardous substance that can be found in drinking water, pharmaceuticals, and even soil.
The plating and mining industries can release cyanide into the air from burning coal and plastics. The metal cyanides can dissociate to release the toxic substance HCN into water.
The use of ion chromatography to characterize, quantitate, and analyze pharmaceuticals for purity, counter ions, and excipients.
Some transition metals have been linked to disease and can contaminate soil or water when disposed of incorrectly.
Consuming high concentrations of biogenic amines such as histamine and serotonin—which are naturally present in many foods—can result in unwanted symptoms.
Weak-acid preservatives are anions widely used to prevent microbial spoilage of acidic foods and beverages. Some require concentrations on food labels.
Halides are binary compounds formed by combining a metal with one of the five halogen elements (chlorine, bromine, fluorine, iodine, and astatine).
Using IC with HPAE-PAD, there’s no need for derivatization or a chromophore.
Excess use of phosphate fertilizers over the last several decades has caused significant water quality and health issues on a global scale, requiring testing for phosphate pollution.
It is important to distinguish between the toxic and nontoxic arsenic forms when measuring arsenic in drinking water or other consumables.
Various industries use organic acids for corrosion treatment and prevention, while beverage industries use them to enhance flavor, color, and aroma, as well as for stability and microbiological control.
Ion-exchange chromatography with suppressed conductivity for amine analyses is ideal for organic amine analysis.

Applications Summary for Analyzing Inorganic Anions and Cations, Toxic Contaminants, and Disinfection Byproducts
Methods for the liquid chromatographic analysis of carbohydrates have often employed silica-based amino- bonded or polymer-based, metal-loaded, cation-exchange columns, with refractive index (RI) or low-wavelength ultraviolet (UV) detection.
