Sample and Po Ports
The sample port fittings are anchored in place to ensure accurate position and orientation, and to
provide a thermal barrier. The P
0
port fitting is attached similarly. The sample port spacing is the same
as the 3020; however, placing of the ports has been altered. A single port is placed in front with the
other two behind for easier access to all three ports. The ports also are extended further below the
upper cabinet base plate for easier operator access and better thermal isolation.
Each sample port has a 20-m frit to prevent sample from entering and clogging the system. The P
0
port is used for continuous saturation pressure measurement.
The gaskets used in the sample and P
0
ports are silver-plated, VCR 316 SS. The gasket for the sample
port contains a filter, while the one for the P
0
port is ridged and snaps into place.
