Varying
Sensitivity Setting
In Figure B.14 we have overlaid the 1
°
C/minute
conventional constant heating rate decomposi-
tion of the mixture (curve a) with a dynamic rate
Hi-Res
TM
scan at four different sensitivity
settings (curves b through e). All of the Hi-
Res
TM
scans were run at 20
°
C/minute with a
resolution setting of 5.0. Note that increasing
sensitivity setting increases the sharpness of
each transition, but does not substantially
change the transition temperature.
