Fig. 5. After oligomer growth in halothane (5 mm) for 4 h ( shaded area ), the anesthetic was removed via mixing and degassing after transfer to a larger container. Halothane was no longer detectable in the solution after 4 h. Thioflavin-T fluorescence in aliquots at timed intervals was recorded. The halothane concentration curve shows near-complete elimination after only 1 h.
