What Happened
Unit was left in
manual mode with all
the valves open or the
fill valve open and the
chamber cap off.
Sample outgassing.
Pycnometer leaks.
Why
What To Do
Close all valves, then
attach a new tank of
helium.
Prior to analysis,
remove moisture and
contaminants from
sample. (Refer to
Preparing and
Loading a Sample,
Chapter 3.)
Check cap O-ring for
defects. Regrease or
replace the O-ring, if
necessary.
While in Manual
Mode, with the cap
installed, open all
valves. With helium
flowing through the
pycnometer, actuate the
expansion valve
repeatedly for
approximately 1
minute. This will
remove lint, which
could cause a leak,
from the valve seat.
Repeat the process for
the vent valve with the
inlet and expansion
valves open.
