| Zusammenfassung |
| Solid state vapour pressures of a selection of atmospherically important
substituted dicarboxylic acids have been measured using Knudsen Effusion
Mass Spectrometry (KEMS) over a range of 20 K (298–318 K). Enthalpies of
fusion and melting points obtained using Differential Scanning Calorimetry
(DSC) were used to obtain sub-cooled liquid vapour pressures. They have been
compared to estimation methods used on the E-AIM website. These methods are
shown to poorly represent – OH groups in combination with COOH groups.
Partitioning calculations have been performed to illustrate the impact of
the different estimation methods on organic aerosol mass compared to the use
of experimental data. |
