Calibration
The pressure readings and the calculated volume for the reference and sample cells are shown in the following table:

Table 2

Determination	P1 (psig)	P2 (psig)	P3 (psig)	P4 (psig)	Reference Cell Volume (cm^3)	Sample Cell Volume (cm^3)
1	17.145	6.486	17.204	8.520	90.620	148.923
2	17.172	6.502	16.986	8.415	90.859	149.102
3	17.083	6.471	17.194	8.519	90.986	149.212

Mean reference cell volume: 90.822 cm³

Mean sample cell volume: 149.079 cm³

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

Sample
The pressure readings, calculated volumes and density values obtained for the test item are shown in the following table:
