The IKA AOD 1 decomposition system performs oxidative decompositions of solid and liquid organic samples under pressure in a closed system.
An absorption solution is placed in the digestion vessel, where the halogens (fluorine, chlorine, bromine and iodine) and sulphate are collected. A precise quantitative analysis of sulphur and halogens can be performed using ion chromatography, ISE, photometry or titration.
The vessels are made of a high alloyed steel, which is especially highly resistant against chlorine.
The decomposition vessels inner-walls have been treated in a way, so that a special self-regenerating catalytic surface is present, which provides exceptionally high recovery rates of 98-100% and typical decomposition times of 2 to 3 minutes.
Among others, the decomposition method is described in the following standards:
DIN 51727, DIN EN 14 582, EPA Method 5050, ASTM D808, ASTM E775, ASTM E776, ASTM D3761, ASTM D4208
