42 . DSC 4000 Installation and Hardware Guide
Assuming that all the other components of the purge gas line are installed, you will now
connect 1/8-in. Teflon tubing to the DSC 4000 using a female connector.
The DSC 4000 system purge gas (1 pc) and sample purge gas (2 pcs) connectors are
mounted to the back of the analyzer.
1. Place the 1/8-in. Teflon tubing from your dry purge gas line onto the inlet labelled
system purge gas ALWAYS REQUIRED.
2. Place the 1/8-in. Teflon tubing from your system purge gas line onto the inlet sample
purge A.
If a second sample purge line is desired, connect it to sample purge B (1/8-in. Teflon
tubing).
Connecting purge and system gas lines to the DSC 4000:
NOTE: The dry box purge inlet is only used when an autosampler is installed on the
instrument.
Connect the Cooling Device to the DSC 4000
The DSC 4000 has an integrated cooling system that accepts various types of cold gases and
liquids. In standard configuration, the cooling system operates from ambient to 445 °C.
Normal tap water can be used for the coolant. The recommended cooling system for the
range of –20 °C to 445 °C is the Polyscience Chiller (N537-0220/N5370221, 120 V and 220 V,
respectively).
The Intracooler 2S for DSC 4000 is the cooling device for the range of –65 °C to 445 °C.
The Portable Cooling Device (PCD) can be used to quickly cool the DSC 4000 to ambient
temperature, or to cool below room temperature for occasional subambient measurements.
The PCD (P/N N5202068) can be filled with ice, ice water, liquid nitrogen or any other
cooling mixtures.
NOTE: When operating the analyzer with a cooling device you MUST use a purge gas.
