Abstract: An electronic device 1 for analyzing a gas composition, which is present in an environment A at an environment pressure Pa, is described. The device 1 is portable and comprises a gas sampling module 7, an ion filtering module 8 and an ion detecting module 9. The sampling module 7 is configured to adjust an input gaseous flow Fi of gaseous particles from the environment A and to ionize said gaseous particles and to generate an ion flow I having an ion composition representative of the gas composition to be analyzed. The ion filtering module 8 is configured to controllably select at least one type of ions present in the ion flow I and to generate a corresponding at least one homogeneous ion beam I′. The ion detecting module 9 is configured to measure the intensity of such least one ion beam I′.
