Abstract
The temperature of the condensation point of light hydrocarbons in a gas is quickly determined by heating a frosted mirror placed in a gas swept enclosure up to the evaporation temperature of all the heavy and light hydrocarbons. The mirror is first cooled as quickly as possible to a temperature higher than the presumed condensation temperature for the light hydrocarbons. Then is cooled much more slowly until the appearance of the first condensations on the mirror. Another cycle as described above is started, in which the presumed condensation temperature value is taken as being equal to the condensation start temperature value of the previous cycle.
