The TGA Thermogravimetric Analyzer measures weight changes
as a function of temperature or time. The system allows for
multiple heating, cooling, and isothermal segments to be linked
together to achieve a complex profile. Automatic gas switching is
also supported during the temperature program. The vertical
hangdown design offers stable and smooth weight readings to be
recorded during the experiment. The TGA’s small mass furnace
responds quickly to changes in the temperature profile and cools
down quickly for fast turn around between experiments.
Typical analyses for a TGA include percent weight loss, onset
temperature calculations and residual weight. The TGA utilizes
the advanced easy to use Infinity Pro Windows software. The
acquisition program sets up the experiment and plots the real
time data. The Analysis program performs all calculations and
provides hard copy outputs.
TGA is commonly used to determine characteristics of materials
such as polymers, to determine degradation temperatures,
absorbed moisture content of materials, the level of inorganic and
organic components in materials, decomposition points of
explosives, and solvent residues.
