| Abstract: | In order to sample medium-temperature fumaroles, gases are collected by means of iron or glass tubings and conveyed to the condensation system through glass dewar tubes. One type of condenser was designed for condensate measurement and gas sampling for Radon activity determination; the other, with NaOH absorbing solution, for the S/Cl ratio measurement and the sampling of rare gases. With this method it is possible to obtain precise gas/vapour measurements as well as air free gas samples. |
