Abstract
The invention relates to the measurement of the tritium concentration of the water vapor in air and more particularly the subject of the invention is a method of automatically sampling tritium in the water vapor of air using a cold trap, of the type comprising a first step of condensing the water vapor of the air by cooling over a cold trap and a second step of recovering the ice formed in the previous step in the form of condensation liquid, characterized in that the air is contained in a sampling chamber (1) and is brought into contact with a cold trap (2, 4) which has been brought to a temperature below 0° C. and in that the liquid of the second step is obtained by warming the cold trap.
