In Figure B.18 we analyzed Accent
monosodium glutamate (MSG), a common salt
used for seasoning foods, which has three well
resolved transitions below 500

heating rate scans of MSG at 1 and 20
Curve b shows the result of a dynamic rate Hi-

Res scan at resolution setting 4.0 and sensitiv-
ity setting 1.0. As can be seen by the derivative
of weight loss curves, the Hi-Res
resolution comparable to the 1
