摘要:
This invention relates to a trapping tube characterized in that it is constituted by a shaped tube comprising:a first section or zone of condensation of the separated gaseous phase delivered by the outlet of the chromatograph,a second section or zone of confinement of the condensate of the separated gaseous phase,and a third section or zone of evacuation of the vector gas of the separated gaseous phase. The invention is more particularly applicable to the obtaining of condensates in a small, even infinite quantity.
