What Is Thermogravimetric Moisture Analysis?
The moisture content influences the weight, density, viscosity, refractive index, and electrical conductivity of a material. Methods for testing moisture content tend to exploit one or more of these physical or chemical properties. Direct measurements address the presence of water itself, either through its removal or through chemical interaction. The use of a thermogravimetric moisture analyzer is a way to directly measure the moisture content of a sample by using the loss on drying (LOD) technique. LOD measures the weight of a sample before and after a drying procedure and uses the weight delta to determine the percentage of moisture as the weight removed by the drying process in comparison to the initial weight of the sample.
Typically, this process is done in a drying oven with a balance to determine the initial and final weight of the sample and using a simple mathematical calculation to determine the moisture content ([initial weight – end weight]/initial weight). This process typically takes several hours to complete and is vulnerable to user error. A moisture analyzer works on the same principle but is an automated system that employs a microprocessor-controlled heating element and an analyzer all in one device; by using such a device, the moisture content of a sample can be measured in minutes rather than hours.
