AQF-2100 Combustion ion chromatography system for halides and sulphur analysis
In high temperature, oxidizing conditions, sample composition can be determined by analysis of the combustion products. Under these conditions, halogens are converted to aqueous volatile products which can subsequently be analysed by ion chromatography (IC) to give the concentrations of the individual halides. The sulfur species are oxidised in solution and the resulting sulfate is determined by IC.
Techniques, such as the oxygen bomb method, Schöniger flasks test and the use of Koehler Wickbold Combustion Apparatus have all previously been used to test for halogen and sulphur content. All of these methods are labour intensive and slow, requiring manual handling and transfer of the samples throughout testing procedures. In the majority of cases lengthy method development projects are required to ensure efficient and optimal combustion conditions and skilled scientists are required for effective analysis.
The Mitsubishi AQF-2100 Combustion Ion Chromatography (CIC) system opens up new possibilities in anion analysis as the equipment allows full automation of the combustion process. Solids, highly viscous samples and gases can now be managed and precisely analysed with the appropriate autosampler. Thanks to the unique combustion technology and double optimised tube system, the sample can be combusted completely without specialised knowledge or training.
The CIC system analysis times can be as little as 15 minutes utilising concurrent sample processing and simultaneous determination of halogens and sulphur. The AQF-2100s combination of precision analysis and optimized timing result in increased productivity facilitating faster decision making processes.
