Abstract
A quantitative enrichment of volatile compounds from substances of the macro- to submicro field in a short time is realized by capillary distillation in a system which includes an evaporator vessel, on the bottom of which one or more filter plates are provided and which is connected to a condensing vessel by means of a capillary tube. The presence of filter plate(s) guarantees a uniform and constant boiling which facilitates the quantitative isolation of the volatile compounds.
