The Log10 [Vp(Pa)] for replications I, II and III was -4.22, -4.07 and -4.16, respectively. The mean Log10 [Vp(Pa)] was -4.15. The vapour pressure at 25°C was 6.03 x 10E-5 Pa, 8.51 x 10E-5 and 6.92 x 10E-5 for replications I, II and III, respectively. The mean vapour pressure at 25°C was 7.08 x 10E-5 Pa.

Conclusions:
The mean vapour pressure at 25°C was 7.08 x 10E-5 Pa.
Executive summary:

The vapour pressure of copper glucoheptonate was determined according to the EU Method A.4 (Vapour Pressure) and EPA OPPTS 830.7950 (Vapor Pressure) with the 'effusion method using thermogravimetric analyzer (TGA)' in triplicate. The mean vapour pressure at 25°C was 7.08 x 10E-5 Pa.
