Samples water content determination method, involves filling sample with known volume and known mass in test chamber, closing chamber in gas-tight manner, and detecting internal pressure lying in chamber by pressure sensor
Samples water content determination method, involves filling sample with known volume and known mass in test chamber, closing chamber in gas-tight manner, and detecting internal pressure lying in chamber by pressure sensor
The method involves filling a sample (7) with a known volume and known mass in a test chamber (1). The chamber is closed in a gas-tight manner, and an internal pressure lying in the chamber is detected by a pressure sensor (5). An auxiliary body (6) with a known auxiliary volume is inserted into the chamber or removed from the chamber. A changed internal pressure is measured, and an unknown volume of the sample is determined by the gas pressures and the known volumes. A mass of a liquid portion of the sample and water content is determined.
