Any other information on results incl. tables

Since the measured effects (differences of the weighed analytical product alter effusion) were too small, no formula of regression and no calculated vapour pressure values can be given. The vapour pressure is below 10e -3 Pa.The measuring range of the effusion method is 10e-3 Pa to 1 Pa.
