As can be seen by comparing the derivative of
weight loss curves in Figures B.19 and B.20, the
TM
Hi-Res scan gives improved resolution in the
same time as the conventional scan. This is
possible because the Hi-Res
the taffy sample rapidly during baseline portions
of the scan and slowly during transitions,
resulting in an average heating rate of about
10 ° C/minute. A 200 ° C/minute Hi-Res
this sample takes about the same time as a 20
minute conventional scan while providing
resolution improvement similar to that observed

with the 50 C/minute Hi-Res
