SmithMSI: Smith Moisture Sorption Isotherm

In PUPMSI: Moisture Sorption Isotherm Modeling Program

Smith Moisture Sorption Isotherm

Description

Smith MSI is an empirical isotherm model for curve assessment of water sorption of polymers with high molar mass.

Usage

SmithMSI(WaterAct, AdsorpM, DesorpM)

Arguments

WaterAct	the numerical value of Water Activity, which ranges from 0 to 1.
AdsorpM	the numerical value of the Moisture content of the Adsorption curve, which ranges from 0 to 1.
DesorpM	the numerical value of the Moisture content of the Desorption curve, which ranges from 0 to 1.

Value

the nonlinear regression, parameters, and graphical visualization for the Smith Moisture Sorption Isotherm model.
