This application note demonstrates that AOX can be precisely and accurately determined in wastewater using combustion ion chromatography. Analysis was automated using the Mitsubishi AQF–2100H system in combination with the Dionex Integrion HPIC system with a Dionex IonPac AS18-4μm column.

In this application, Liquid Petroleum Gas (LPG) samples were combusted in the Mitsubishi AQF-2100H system and then fluoride, chloride, and sulfate were determined using the Dionex ICS-2100 Ion Chromatography system with a Dionex IonPac AS15 anion-exchange column set.

When coal is burned, the exhaust contains halogens that can be released into the atmosphere as acid gases such as hydrogen chloride (HCl) and hydrogen fluoride (HF), which can harm vegetation, animals, and infrastructure directly or cause acid rain. In this application note, coal samples were combusted in the Mitsubishi AQF-2100H system and then fluorine and chlorine were accurately and precisely determined using the Dionex ICS-2100 Ion Chromatography System with a Dionex IonPac AS15 anion-exchange column set.

Polyethylene (PE) is widely used for containers, packaging material, etc. Because halogen compounds are often used as additives, it is important to know the halogen content when disposing or recycling PE products. By using a combustion ion chromatography (CIC) system consisting of the automatic quick furnace AQF-2100H and an ICS-1600 ion chromatograph, the concentrations of halogens and sulfur can be determined accurately and quickly.

Wood chips are used for producing paper and are also contained in waste deposits. It is important to know the halogen contents of wood chips for impurity management in paper production and for environmental assessment in waste materials. By using a combustion ion chromatography (CIC) system consisting of the automatic quick furnace AQF-2100H and an ICS-1600 ion chromatograph, the concentrations of halogens and sulfur can be determined accurately and quickly.
