Metrohm experts have published an application bulletin that describes the determination of water in non-explosive and non-flammable gaseous samples with the coulometric Karl Fischer method. This method is ideal for very low water contents.For gases with a high water content (> 50 ppm), a generator electrode without diaphragm can be used. For gases with a water content below 50 ppm, a generator electrode with diaphragm has to be used, as otherwise the results will be too high.
