ABSTRACT:
An apparatus for controlling the flows of products of decomposition in a thermogravimetric procedure such that condensation on the support for a sample and on the chamber is minimized. A mixing chamber is established about a portion of the sample support that is open to the region of the sample such that products of decomposition can enter within the hot zone about the sample. A purge gas is fed into the interior of the mixing chamber, also the hot zone, but spaced apart from the end closest to the sample. The gases commingle within the mixing chamber and are extracted from the thermogravimetric chamber via outlets in a cooler region.
