Eigenschaften
Perfluoroctan ist eine farblose bis gelbliche FlΓΌssigkeit, die unlΓΆslich in Wasser ist.cite-ref-sigma-1-7[1]
Verwendung
Perfluoroctan wird (wie auch Perfluordecalin) bei der operativen Behandlung einer NetzhautablΓΆsung am Auge als mechanisches Hilfsmittel, um die Netzhaut faltenfrei an den Augapfel anzudrΓΌcken, verwendet.cite-ref-g-nter-fred-fuhrmann-4-0[4]
Analytik
Perfluoroctan kann mittels Massenspektrometrie nachgewiesen werden. Als Ionisierung eignen sich hierbei plasmabasierende Methoden, wie APCI oder DBDI.cite-ref-8[8]
