Connecting Gas Lines
The GAS 1 port on the Discovery DSC provides a constant base purge and controlled cell purge; the GAS
2 port is for cell purge only and can be used with helium to purge the cell. The cooling head secondary
purge is connected through the COOLING GAS connection. By default, there is no purging of the interior
of the LN Pump cooling head; however, an option exists in TRIOS software to automatically purge the
interior of the LN Pump cooling head when the cell is open during loading/unloading of samples (while
under DSC Autosampler control) and during cell conditioning. Refer to TRIOS Online Help for more
information.
Follow the instructions below to connect the purge lines.
