Pressure Equilibrium
Difference between adjusting equilibration rate and time
options.
The AccuPyc III obtains density from the volume calculated
from measuring pressure differences. Allowing the pressure to stabilize before
moving on is a crucial step in achieving precise and repeatable results.
Pressure stabilization can be controlled through the instrument.
Pressure equilibrium delay can be
controlled by a set rate or time interval:
A high rate can produce results faster but may not be as
precise as desired.
A low rate may cause errors when some materials are analyzed,
such as some organics.
A fixed time interval moves on to the next step when the
specified time has been reached.
