Combustion Ion Chromatography - Straightforward Determination of Halogens and Sulphur in Solid and Liquid Samples

摘要

The cooperation between Metrohm and Mitsubishi opens up new possibilities in analysis. Solids and highly viscous samples can now be analysed fully automatically, whereas in the past - e.g. with the oxygen bomb - a good deal of manual work was required. The advantages of Combustion IC include the fullyrnautomated simultaneous determination of halogens and sulphur. Combustion IC works very precisely and with optimised timing, allowing a high sample throughput.rnIn a fully automated process the samples are thermally digested under argon in the furnace unit and then combusted with oxygen. The resulting gaseous compounds are passed into an absorption solution, which is then transferred inline to a Metrohm ion chromatography system.rnWith the help of the appropriate autosampler it is possible to save time when measuring both liquid and solid samples: at the same time as a chromatogram is being recorded, the next sample is already being digested.
