In a method and an apparatus for sampling gas for analysis purposes from a hot dust-filled gas stream, e.g. smoke gases from industrial plants, the sampling is carried out continuously using a gas sampling probe without the use of a coolant, said probe comprising a gas inlet section (1), a filter section (8) and a gas outlet section (9) connected to a gas pump (6), and wherein the filter section (8) is embedded in a filter housing (3) with an outlet (4) for the purified sample gas portion to be analyzed, and the probe being furthermore provided with a dust activation device (5) which activates the dust particles suspended in the gas in such a manner that the particles are constantly prevented from depositing or forming bakings in the interior of the probe and thus clogging it.
