Evolved gas analyses of model inorganic compounds and apatites are describe
d. The measurements are performed on the system - a 'thermochromatograph' (
ThGC) - with a low-volume, thermal furnace, interfaced to a capillary gas c
hromatograph (GC) via a computer-controlled, pneumatic sample inlet device
in the 70-600 degrees C region. The 'information content' performance of th
is inherently simpler system is comparable to that of TG/GC/MS and TG/GC/IR
systems when similar materials are analyzed. (C) 1998 Elsevier Science B.V
