Executive summary:

A Vapour Pressure Determination (Gas Saturation Method: U.S. EPA Product Properties Test Guidelines OPPTS 830.7950) was conducted in triplicate using vapour saturator columns containing test substance treated sand. The test was done with 10 mL/min and 8 mL/min flow rates of nitrogen gas to flush the vapours from the colums into traps. The traps were then extracted, the contents analyzed by HPLC and the vapour pressure calculated.

The vapour pressure was determined to be 0.354 ± 0.010 Pa at the 10 mL/min flow rate and 0.408 ± 0.014 Pa at the 8 mL/min flow rate.
