Abstract

This article compares the performance of an NMR-based and a microwave-based moisture measurement instrument designed for biomaterials. The conventional moisture measurement method, Loss-on-Drying, serves as a reference measurement for both instruments. Six different biomaterials at three moisture content levels were measured with the microwave instrument and five biomaterials were measured with the NMR instrument. After instrument calibrations, the difference and variation of the measurement results for parallel samples and the repeatability of measurement results obtained by the NMR and microwave instruments were estimated. Reasonable agreement between the measurement methods was achieved.
