ABSTRACT:
A heavy concentration of volatile substances and high degree of purity are achieved in a short time in a closed system by transferring the volatile substances from a vessel containing the gas phase into a condensation vessel by means of a capillary with a small inner diameter. Preferably there is a temperature drop from the vessel containing the gas phase to the condensation vessel.
