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.
