Are you referring to the changes in water content as temperature drops, or to precise laboratory analyses? If calculations are needed, many books provide methods for doing so based on Dalton’s law of partial pressures; such information can also be found in laboratory analysis textbooks.

Is it the analysis of trace moisture in chlorine gas? Tangshan Sanyou Chlor-Alkali uses the micro-water analysis system from Beijing Chuangjie New Century, and it performs well – an online micro-water analysis instrument!
There are two methods available now: 1. Conventional analysis, in which phosphorus pentoxide is placed in a glass tube to absorb the moisture from chlorine gas； 2 Using instrumental methods, there are those for online analysis and those for use in laboratories. I have a moisture meter for use in the laboratory, and it works quite well. The moisture content in chlorine gas is generally below 50 ppm. Conventional analysis requires high operational precision and suffers from significant errors; it is practically useless for concentrations below 150 ppm.
