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.

Oil extracted from fish and algae is a renewable alternative to petroleum-based sources. If this oil is used as a lubricant, chloride needs to be monitored and its level minimized to reduce the likelihood that corrosive HCl will form. By using a combustion ion chromatography (CIC) system consisting of the automatic quick furnace AQF-2100H and an ICS-2100 ion chromatograph, the concentration of chloride can be determined accurately and quickly.

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.
