Mean reference cell volume: 90.910 cm3
Mean sample cell volume: 149.126 cm3
As the reference cell volume and sample cell volume were within the defined tolerance (90.953 ± 1.0 cm3and 149.225 ± 1.0 cm3 for the reference and sample cell volumes respectively) the gas comparison pycnometer was therefore considered acceptable for use.
