Gas Delivery Module
The Discovery DSC™ gas delivery module controls the flow and delivery of purge gas to the Discovery
DSC cell. It is based on a manifold design, and is capable of switching between two different purge gases
at any point during or between experiments. It also measures the base purge flow, which prevents frosting
when cooling accessories are used, and switches on/off the cooling gas flow.
DSC Autosampler
The Autosampler (shown below) is standard on the TA Instruments Discovery DSC2500, and optional for
the Discovery DSC25 and DSC250.

The Autosampler is a four-axis robotic device that automatically loads sample and reference pans between
the DSC measurement cell and the Autosampler tray. Once the Autosampler loads the pans and the cell
covers are in place, the controller takes over and runs the pre-programmed thermal analysis experiments.
After the experiment is complete and the cell returns to standby temperature, the instrument uncovers the
cell and the Autosampler then unloads the pans. The unattended process can be pre-programmed to run up
to 53 samples with one reference pan.
Cooling Accessories
The Discovery DSC operates in conjunction with one of the cooling accessories listed below. Your choice
of cooling accessories depends on the temperature range that you wish to use for your experiments. For
information on installing the cooling accessories, see
. For proper operation, the correct cooler
type must be selected through the instrument control software; see the online help for details.
WARNING: Do not place your hands in the path of the Autosampler when it is in motion. Physi-
cal injury may occur.
AVERTISSEMENT: Ne placez pas vos doigts sur le chemin de l'échantillonneur automatique
lorsqu'il est en mouvement. Des blessures physiques peuvent se produire.
