Abstract
Apparatus for conducting thermogravimetric analysis continuously when sample weights are measured automatically in the case of measurement of a plurality of samples. A plurality of empty sample containers are transferred individually in succession from a tray to a thermobalance, where each container is weighed and a representation of the weight of each empty container is stored in a first memory. Then, a sample is loaded into each container in the tray and the loaded sample containers are transferred individually in succession from the tray to the thermobalance where each loaded container is weighed and a representation of the weight of each container is stored in a second memory. The weight of each sample is then determined based on the difference between the representations stored in the first and second memories.
