The invention relates to a device for preparing a gas flow for introduction thereof into a mass spectrometer, wherein the gas flow contains one or more analytes and has helium as carrier gas. According to the invention, a selective separating device is provided for separating off a part of the carrier gas from the gas flow (), to form a residual gas flow () and a separated carrier gas flow (). A higher fraction of the analyte is present therein than in the gas flow and in the separated carrier gas flow there is a lower fraction of the analyte.
