Ion chromatography is a specialized technique used to separate and analyze ions in a sample. It involves the use of a specialized column and eluent to isolate specific ions based on their chemical properties. This technique is commonly used in environmental, pharmaceutical, and food analysis to determine the concentrations of various contaminants or active compounds. Ion chromatography requires specialized skills and equipment to effectively separate and analyze ions, making it a valuable tool for researchers and scientists in a variety of fields.
