A Virial-type Thermal Equation

A virial-type thermal equation is an empirical model that was developed to yield an improved fit versus traditional Langmuir isotherm modelling.  It is often useful for describing heterogeneous systems.  The virial-type thermal equation approaches the Henry region at infinite dilution.

virialThe Henry’s constant make be calculated from virial-type expansion.

virialHL The virial-type thermal equation has been added to MicroActive to allow users greater flexibility for modelling their experimental isotherm data.
