Humidity-Controlled Thermogravimetric Analysis
A Mettler-Toledo Humidity controlled ThermoGravimetric Analyser (HTGA) is used to determine the deliquescence relative humidity (DRH) of dry samples as a function of temperature. This information is needed to determine the conditions under which dry particles will spontaneously absorb moisture in the atmosphere, which can lead to cloud formation. Additionally, we can measure the concentration of solutes at the deliquescence point by simultaneously measuring total mass as the particle deliquesces.
With this technique we are able to study samples in a temperature range applicable from the lower to the upper troposphere: 35 Celsius to -20 Celsius.
