Description

Gives methods for the determination of water using an analyzer with an in-line sensor in gaseous flows of the substance to be analyzed. Compiles the various principles of working of the most generally used commercial analyzer like electrolytic decomposition – light reflection on a cooled mirror (dew-point) – modification of vibration frequency of a quartz crystal covered with a hygroscopic layer – variation of the capacity of a capacitor formed by a hygroscopic dielectric polymer and two porous electrodes – infrared spectrometry – Micro-wave absorption measurement – variation of the capacity of a capacitor consisting of an aluminium oxide dielectric covered by an evaporated porous gold film.
