FlowSorb III

Preparing the FlowSorb for Idle Periods

If the FlowSorb is to be inoperative or unattended for a period long enough for
the liquid nitrogen in the Cold Trap Dewar to evaporate (or the dry ice to evapo-
rate from the dry ice acetone slurry), remove the Dewar and U-tube so that impu-
rities are not released into the system. Install a clean, dry U-tube after removing
the current one. If additional U-tubes are unavailable, clean the current tube and
allow to dry; then reinstall at the Cold Trap position.
If the FlowSorb is going to be idle only for a couple of days, reduce the gas
flow to approximately one-quarter of its normal value and leave power ON. The
gas loss and power drain are very low and the instrument will be immediately
ready for use.
Regardless of how long the FlowSorb is to be idle, keep a sample holder with
sample tube installed at both the Degas and Test ports. This ensures the integrity
of the system for gas flow and prevents infusion of water and other vapors.
