Since the analysis was conducted under high vacuum conditions, the heat
could be transferred only by radiation, this caused a consistent
difference between the furnace temperature and the sample one and a
considerable time for the system to reach equilibrium.
The temperatures reported (registered by the thermocouple under the
Knudsen cell) are hence different from the one set and the mass loss has
been measured only in a 80 minutes time interval within each isotherm,
after the system had reached equilibrium.
The first seven isotherms were discharged since the mass loss was too
low to be accurate.

Extrapolation at 20°C
The vapour pressure of the test item, Balsalazide acid was determined
according to OECD Guideline 104 and EC Method A.4 and was estimated to
be 3.80E-05 Pa at 20°C.
