Calculating osmotic pressure of glucose solutions according to ASOG model and measuring it with air humidity osmometry

The osmotic pressure of glucose solution at a wide concentration range was calculated using asog model and experimentally determined by our newly reported air humidity osmometry. the measurements from air humidity osmometry were compared with the well-established freezing point osmometry and asog model calculations at low concentrations and with only asog model calculations at high concentrations where no standard experimental method could serve as a reference for comparison. results indicate that air humidity osmometry measurements are comparable to asog model calculations at a wide concentration range,while at low concentrations freezing point osmometry measurements provide better comparability with asog model calculations.
