Reference
No statistical analyses were performed because the balance readings were too low and variable for a line of best fit to have any meaning. Instead it was considered more appropriate to impose a regression slope on a chosen data point to provide an estimate of maximum value for vapour pressure at 25 °C. Run 5 was chosen because the sample had been under vacuum for the longest period prior to this run and so degassing would have been the most complete. The reading at 127 °C (400.15 K) was chosen because this is the data point which gives the highest estimated vapour pressure at any given temperature when a slope of -1500 K is imposed upon it. The value of -1500K is an in-house value and is the shallowest slope observed whilst determining the vapour on a wide range of samples using the vapour pressure balance method. Extrapolation to 25°C gave a vapour pressure of 6,909 x 10 -3Pa which has been taken as a maximum for this material.
