Halides are binary compounds formed by combining a metal with one of the five halogen elements (chlorine, bromine, fluorine, iodine, and astatine). Many of these compounds will dissolve in water, and because of this solubility, they usually occur only under special conditions. The most common halide compound is sodium chloride (NaCl), also known as rock salt.
Compared to standard wet chemical techniques, ion chromatography (IC) offers improved speed and accuracy for halide analysis. Using suppressed conductivity lowers the background conductivity caused by the eluent and effectively increases the conductivity of the analyte. Common inorganic anions such as fluoride, chloride, bromide, and sulfate can be resolved in the same injection, as well as common organic anions.
