Abstract: A portable system 1 for analyzing gaseous flows that vary over time is described, the system comprising a sampling chamber 18, a gas sampling module 7, an ion filtering module 8 and an ion detecting module 9. The sampling chamber 18 is suitable to be kept at a controlled sampling pressure Pc, and is configured to receive at least one gaseous flow F having a gaseous composition to be analyzed that is variable over time. The gas sampling module 7, arranged in fluidic communication with the sampling chamber 18, is configured to adjust an input gaseous flow Fi of gas particles from the sampling chamber 18, and an output gaseous flow Fo from the sampling module 7, so as to reproduce inside the sampling module 7 a gaseous composition representative of the gaseous composition to be analyzed. The gas sampling module 7 is further configured to ionize said gas particles and to emit the produced ions, so as to generate an ion flow I having an ion composition representative of the gaseous composition to be analyzed. The sampling module 7 is also suitable to maintain inside it a controlled ionization pressure Pi, and it is also configured in such a way that the input gaseous flow Fi comprises a plurality of micro-flows at a molecular or predominantly molecular regime, at the sampling pressure Pc, and the output gaseous flow Fo is a flow at a molecular or predominantly molecular regime, at the ionization pressure Pi. The ion filtering module 8 is operatively connected to the sampling module 7 to receive the ion flow I, and is configured to controllably select at least one type of ion present in the ion flow I and to generate a corresponding at least one homogeneous ion beam I′, having an intensity representative of the concentration of the corresponding gas particle in the gaseous composition to be analyzed. The ion detecting module 9 is operatively connected to the ion filtering module 8 to receive the at least one ion beam I′, and is configured to measure the intensity of the at least one ion beam I′ and to generate a corresponding electric signal S representative of the concentration of the corresponding gas particle in the gaseous composition to be analyzed.
