It is a complete Karl Fischer solvent that contains sulfur dioxide along with the buffer- ing agents so it can be used directly in the titration vessel. You won’t need to go through the hassle of mixing the buffer with a solvent in order to use it. This is a great time-saver that also increases the consis- tency of your analysis, and it can be used with either the Single Solution or the Two- Component systems.
