Thermogravimetric determination of the moisture content in native samples with the aid of HR 83 (Mettler Toledo) analyser is based on the concept of halogen heating and an automated monitoring of the course of the kilning curve. The possibility of utilizing this instrument in the field was tested on real samples of barley, green malt and malt. Validation of the methods for determining dry matter in barley, green and finished malt was performed. Based on the obtained observations, it can be stated that this instrument can be recommended to malting and brewing laboratories.Thermogravimetric determination of the moisture content in native samples with the aid of HR 83 (Mettler Toledo) analyser is based on the concept of halogen heating and an automated monitoring of the course of the kilning curve.
