PUPMSI (version 0.1.0)

BradleyMSI: Bradley Moisture Sorption Isotherm

Description

Bradley model is a two-parameter isotherm model that measures polar nature of sorptive surfaces.

Usage

BradleyMSI(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 Bradley Moisture Sorption Isotherm model.
