Our TG apparatus enables thermogravimetric measurements to be carried out in highly aggressive atmospheres, at high pressures, in steady atmospheres or flowing media - and with many more advantages besides! No condensation occurs, no flushing gas is needed. Long term measurements over several months are possible with a reproducibility better than 0.03mg. Samples of a few mg up to over 500g can be weighed / measured at temperatures up to 1400K and pressures up to 10MPa. (2300K and 60MPa in special versions). All this is made possible by using magnetic suspension balances for the contactless force transmission from a closed measuring cell through a wall to a microbalance located under normal atmospheric conditions.
