Advanced Hi-Res
TM
Techniques
This section discusses in greater detail how to
use the Hi-Res
TM
features and gives specific
advice which may be helpful in setting up your
own experiments. As with any new analytical
tool, there is a learning period required during
which the user becomes familiar with the
options and adjustments and gains knowledge
about what can and cannot be expected from the
analysis.
What Can Be Resolved
and What Cannot?
Will Hi-Res
TM
TGA improve the resolution of
my transitions? This is one of the first ques-
tions asked by most people when they are
introduced to Hi-Res
TM
TGA. It would be
wonderful, if the answer were always an un-
qualified yes. Unfortunately, there are some
applications where resolution enhancement will
be minimal. Therefore, some criteria for select-
ing likely candidates for resolution improvement
is needed. Outlined below are some guidelines
which can be employed whenever a new mate-
rial is considered, or when a sample is tried and
no resolution improvement is obtained. (It is
worth noting that substantial productivity gains
are still possible, even if transition resolution is
not improved.)
