Model 1305 MultiVolume Pycnometer
and equation (9) rewritten as
Equation (12) then becomes the working equation for the MultiVolume Pycnome-
ter 1305. Calibration procedures are provided to determine V
the pressures are measured by a gauge pressure transducer. Provisions are made
for conveniently charging and discharging gases at controlled rates, for optimizing
the relative sizes of the sample chambers and expansion volumes, and for cleans-
ing the samples of vapors which would render equations (1), (2), and (3) inade-
quate to describe the pressure behavior.
