The equipment images in this topic may differ slightly from your equipment; however,
the instructions are the same unless otherwise noted.
A frit is located in the connecting nut attached to each analysis port. If the frit becomes
contaminated, the contaminant may adsorb or desorb during analysis, affecting the results. A
contaminated frit on the analysis port may be indicated as a leak or a free space reading much
lower than normal.
Use the proper size frit for the sample port. The analyzer will not operate properly if an
incorrect size is used.
1. Go to Unit [n] > Enable Manual Control. Ensure a checkmark displays to the left of the
menu item. If the analyzer schematic does not display, go to Unit [n] > Show Instrument
Schematic.
2. Right click on the valve of the appropriate port. If the valve is open, click
valve.
3. Use a wrench to remove the connecting nut from the sample port. Pry out the filter (frit) and
O-ring.
To avoid degassing problems, the frit should be clean and should not be touched with
bare hands.
