Combustion Ion Chromatography – Straightforward Determination of Halogens and Sulfur in Solid and Liquid Samples
The cooperation between Metrohm and Mitsubishi opens up new possibilities in analysis. Solids and highly viscous samples can now be analyzed 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 fully automated simultaneous determination of halogens and sulfur. Combustion IC works very precisely and with optimized timing, allowing a high sample throughput.
	The principle of Combustion IC In a fully automated process the samples are thermally digested under argon in the furnace unit and then com-busted with oxygen. The resulting gaseous compounds are passed into an absorption solution, which is then transferred inline to a Metrohm ion chromatography system. Time saving With 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. Broad range of applications Among other possible fields, Combustion IC can be highly useful in quality control of raw materials, intermediates and finished products. In the environmental field Combustion IC can be used to monitor compliance with standards such as ASTM D 7359-08, DIN EN 228, IEC 60502-1, RoHS, WEEE and others.
