Determination of Equivalent Weight and Ion-exchange Capacity (IEC) of ion-exchange materials

Humidity-dependent dynamic water (mass) uptake of ionomers and hydrophilic materials at a controlled temperature (20-85C) to determine sorption isotherms, dynamic diffusion coefficients, residual water. Also works with select organic solvents (vapors)

Measure mass change with heating to determine the residual water loss (dehydration at high temperature), mass loss, thermal decomposition at high temperatures
