TGA 2950 2–9
Choosing
a Location
Because of the sensitivity of TGA experiments,
it is important to choose a location for the
instrument using the following guidelines. The
TGA should be:
In ... a temperature-controlled area.
... a clean, vibration-free environ-
ment.
... an area with ample working and
ventilation space.
On ... a stable work surface.
Near ... a power outlet (115 volts AC,
50 or 60 Hz, 15 amps). A step
up/down line transformer may
be required if the unit is oper-
ated at a higher or lower line
voltage.
... your TA Instruments thermal
analysis controller.
... compressed lab air and purge
gas supplies with suitable
regulators and flowmeters.
Away
from ... dusty environments.
... exposure to direct sunlight.
... direct air drafts (fans, room air
ducts).
... poorly ventilated areas.
... noisy or mechanical vibrations.
Drying out the instrument may be needed, if it has
been exposed to humid conditions. It is important
to be certain that the instrument ground is
adequately connected to the facilities ground for
safe operation.
Run the following method to dry out the instrument
(refer to Chapter 4 for further information):
1 Ramp at 10°C/min to 400°C
2 Isothermal for 30 min.
