Combustion Ion Chromatography (CIC) is an automated technique to determine at wt.ppm – wt.% range, halogens (fluoride, chloride, bromide, iodide) and sulfur in a wide scale of samples, like coolants for mechanical engineering, recycled materials, and many others. It combines a combustion system with the analytical separation precision of an Ion Chromatograph. Since it is automated, it reduces time and labor by eliminating complex sample preparation steps. It also eliminates the use of hazardous chemicals applied during acid digestion or back extraction. Analyses can be carried out according to ASTM, ISO or DIN standards. During combustion IC, a small amount of sample is completely oxidized by pyrohydrolytic combustion in an oxidizing atmosphere (argon / oxygen) at elevated temperature. Halogens (X) are converted to HX and/or X₂, and Sulphur to SO_x. The released vapors are absorbed in an aqueous solution. The halogens and SO_x are then converted to F^–, Cl^–, Br^–, I^– and SO₄^2-. Subsequently, the sample solution is automatically injected into an IC system, where ions are separated based on different affinity towards an analytical column. Detection takes place by using a conductivity detector. Quantification is done by comparing intensities measured with those of certified calibration standards.
