It is suggested to carry out thermogravimetric measurements at pressures between 1 and 100 torr. In this pressure range thermal gas flow will cause only small disturbances, and the gas evolution will be much less inhibited by the surrounding gas than at higher pressures. In a thermal analysis of calcium oxalate, carried out with an apparatus containing a pressure controller, the weighing disturbances were reduced to a few micrograms.
