5. Moisture Vaporization
With this method, the coulometric titration system is used in conjunction with
a moisture vaporization system. Approximately 150ml of anolyte
(Aquamicron AX or AS) is placed in an electrolysis cell. Two ampoules
(10ml) of catholyte (Aquamicron CXU) are used.
The condition for moisture vaporization should be optimized for the
particular sample. Detailed instructions for various types of samples are
provided later in this manual.
