Abstract

A highly sensitive, continuous-reading electrolytic hygrometer capable of measuring water concentrations in a gas stream down to ppm levels has been coupled to a Stanton-Redcroft DTA 671B Differential Thermal Analyser. The method of coupling and operating precautions are described. Integration of the EGA peaks obtained shows the combination to be capable of measuring sub-milligram quantities of evolved water to an accuracy of better than 4% Applications discussed include hydrate decomposition and degradation of plant acids used in the food industry.
