Generator Electrode with Diaphragm for HI904 – HI900511
The HI900511 is a coulometric generator electrode with diaphragm for the HI904 Karl Fischer titration system. The glass diaphragm separates the anode from the cathode preventing anode-generated iodine from being reduced at the cathode as part of the coulometric reaction. This system is ideal for extremely low water content, nitrogenous compounds and easily reduced samples.
