Conclusions:
The mean vapour pressure of HGA Ca (1:1) L was 0.0517 Pa at 25 °C.
Executive summary:

This study was performed to determine the vapour pressure of HGA Ca (1:1) L by the effusion method using thermogravimetric analyzer. The study was conducted in compliance with OECD 104 guideline and the OECD Principles of GLP (1998). The Log10 [Vp(Pa)] of HGA Ca (1:1) L for replications I, II and III was -1.30, -1.27 and -1.29 respectively. The mean Log10 [Vp(Pa)] was -1.29 .The vapour pressure of HGA Ca (1:1) L at 25 °С was 5.37 x 10E-2 Pa, 5.01 x 10E-2 and 5.13 x 10E-2 for replications I, II and III respectively. The mean vapour pressure of HGA Ca (1:1) L was 5.17 x 10E-2.
