β¦ Synopsis
An experimental technique to determine orthobaric surface tensions of both pure and mixed liquefied gases by the differential capillary rise method at cryogenic temperatures is described. The apparatus has been tested with measurements performed on the ethene+ethane system, from 117 to 135 K.

With a view to investigating the surface tensions of a (non-alkane+perfluoroalkane) mixture which, in a similar fashion to a typical (alkane+perfluoroalkane) mixture, displays large positive deviations from bulk ideality and large negative deviations from surface ideality, we have determined the ort
