Hello everyone,

I might be asking the impossible, but I was wondering if there is a model to convert atmospheric boiling points of n-paraffines to boiling points under high vacuum. Or if there if these values are known.

I am working with a DT-MS (direct temperature resolved MS) and I want to calibrate the pyrolysis probe temperature with a n-paraffine standard (up tp C40). Because now I can only change the current of the filament, without knowing the temperature.

I also realise that it might not be possible to exactly know the temperature with this calibration method. However, it would be nice to have some indication of the probe temperature when I'm analysing samples.
