KARL FISCHER REAGENT Pyridine Free
The pyridine-free Karl Fischer reagent consists of two solutions, a dissolving agent and a titrating agent. The dissolving agent contains sulfur dioxide and a pyridine substitute in a solvent and is used for taking up the sample to be investigated with respect to its water content.
An essentially pyridine-free Karl Fischer reagent useful in the determination of water, comprising a dissolving agent containing sulfur dioxide and a pyridine substitute in a Karl Fischer solvent, and a titrating agent containing iodine in a Karl Fischer solvent, wherein the pyridine substitute is an alkali or alkaline.
Karl Fischer Reagent (Pyridine free). single soln for titrimetric determination of water 1 ml reagent ~5 mg water.
The analysis of the water content of a sample by Karl Fisher titration can be carried out using a volumetric method or a coulometric one.
