A fluid sampling system and a method thereof are provided. The fluid sampling system is provided with a plurality of sampling channels, each of the sampling channels comprising a sampling line having an inlet, a regulated outlet, and first and second calibrated flow orifices connected in series between the inlet and outlet. Each of the sampling channels also comprises a controllable derivation line connected between the first and second orifices, for deviating fluid from the sampling line. The fluid sampling system is also provided with a connecting line for connecting together the outlets of the sampling lines. The connecting line has a main regulated outlet for providing a fluid sample. The fluid sampling system also comprises control means for controlling pressures between first and second orifices of all of the sampling lines by means of the controllable derivation lines, thereby increasing pressure between first and second orifices of one of the sampling lines which is then selected to provide the fluid sample to the outlet of the connecting line, and decreasing pressure between first and second orifices of remaining sampling lines to back purge the remaining sampling lines. Such a fluid sampling system does not contaminate the sample by the product that is out gassed or adsorbed by the control means used to control fluid flows.
