Setting Up System Communication
In order to connect the instrument to a network, you will need to connect the controller computer to a
router, then connect the computer to a LAN.
Refer to the TRIOS Software Installation Instructions for more details.
Connecting Lines to the Gas Delivery Module
It is important to accurately control the sample atmosphere during Discovery TGA experiments. This is
achieved by connecting purge gases to the system. Purge gas is distributed separately to two parts of the
TGA: the furnace (sample) and the balance chamber. The Discovery TGA is equipped with Gas Delivery
Manifold (GDM) to control the flow rates of the gases. Nitrogen is typically used for
GAS 1
. Follow these
instructions to connect the purge lines. Refer to
Connecting Purge Gas Lines
CAUTION: Do not use any liquid in the purge lines.
MISE EN GARDE: N'utilisez aucun liquide dans les conduites de gaz de drainage.
NOTE
: If you are using a “house” laboratory supply rather than bottled gas, it is highly recommended that
you install an external drier and a 5-µm filter.
1
Locate the
GAS 1
port on the back of the Discovery TGA. The
GAS 1
port is used to purge both the
sample and balance areas. As such, an inert gas such as nitrogen should be used in this port.
2
Locate the
GAS 2
port. The
GAS 2
port is also used to purge the sample area and is used when a purge
gas other than
GAS 1
is desired or when gas switching during an experiment is needed.
DANGER: The gas delivery module (GDM) o-rings (on the interior of the GDM) are sealed using
Krytox
®
vacuum grease. This grease may be harmful or fatal if ingested. Avoid contact with eyes
and skin. For additional important safety information, refer to the Krytox MSDS.
DANGER: Les joints toriques (à l'intérieur du GDM) du module d'alimentation en gaz (GDM) sont
scellés à l'aide de la graisse à vide Krytox®. En cas d'ingestion, cette graisse peut être nocive
ou fatale. Évitez tout contact avec la peau et les yeux. Pour obtenir des renseignements supplé-
mentaires sur la sécurité, reportez-vous à la fiche technique santé-sécurité du Krytox.
WARNING: Use of flammable or explosive gas as a purge gas is dangerous and is not
recommended for this instrument.
AVERTISSEMENT: L'utilisation d'un gaz inflammable ou explosif comme gaz de drainage est
dangereuse et n'est pas recommandée pour cet instrument.
