TA Instruments TGA 2950 - Overview

TA I NSTRUMENTS TGA 2950 B–5
Hi-Res
TM
Option
Overview
This appendix describes how to use the High
Resolution option for the TGA 2950 instrument.
Some of the benefits provided by the Hi-Res
TM
option are:
· Improved Transition Resolution
· Faster Survey Scans
· Enhanced Signature Analysis Capability
· Transition Temperatures Closer to
Isothermal Values
· Increased Method Programming Versatility
The Hi-Res
TM
option provides three method
programming steps (segments) which are used
for the high resolution TGA capability. The
new method segments are:
· High Resolution Ramp
· High Resolution Sensitivity
· Abort Next Segment
With the addition of these segments, method
programming becomes more versatile and
powerful than ever before. The Hi-Res
TM
ramp
can be used alone as a simple single-segment
method, or the method segments can be com-
bined with more traditional segments, such as
constant heating rate ramps and timed isother-
mal periods, for maximum programming flex-
ibility.
What these segments do and how to use them to
control TGA experiments and improve transition
resolution is described in the following sections.
