Any other information on results incl. tables

Three trials were conducted and five points were recorded for each trial.

Log10 (Vapour Pressure (Pa)) was plotted against reciprocal temperature and values of vapour pressure were calculated at 20°C and 25°C with the linear function parameters (slope and intercept):

Calculated values respect validity criteria (less than 20% of difference) and the linear functions obtained own a correlation coefficient R² over 0.95 for trials 2 and 3.

Moreover the calculated values showed good correspondence with the experimentally determined ones.

In conclusion, the vapour pressure of HEMATOXYLIN HPL is 2.22x10-5 Pa at 20°C and 4.62x10-5 Pa at 25°C.
