FlowSorb III
Both FlowSorb III models permit the measurement of surface area by a single-
point and multipoint determination. It is essential that you become familiar with
the single-point test before attempting a multipoint analysis.
Preparing the FlowSorb for Operation
For best results, the FlowSorb should be free of air before performing analyses.
It is not necessary to purge air from the system before every analysis. Purging
should be performed when the FlowSorb III:
•
is initially put into operation
•
has been idle for several days
These instructions assume the FlowSorb has been installed as described in Chap-
ter 2, Installation.
Remember to use caution when handling Dewars. Refer to Precautions in
Chapter 1 for a list of recommended precautions.
1. Install an empty sample tube in a sample holder (refer to Installing a Sam-
ple Tube in Chapter 2). Be sure the sample tube is fully inserted and that
the seals on both stems are secure.
2. Install the holder onto the instrument in the Test position, making sure that
it snaps fully into place.
3. Install an empty sample tube in a sample holder, then install the sample
holder onto the instrument in the Degas position
4. Install a U-tube in the Cold Trap position, being sure both stems are fully
inserted and securely sealed.
