1. A method of detecting a location of a gas leak within a test region, the method comprising:

  • (a) providing a sensor array comprising a plurality of sensors configured to measure a plurality of gas concentrations simultaneously;

    (b) measuring the plurality of gas concentrations at the same time, while maintaining a position of the sensor array;

    (c) determining a local gas concentration profile based on the measured gas concentrations;

    (d) moving the sensor array to a new location depending upon the local gas concentration profile determined in step (c); and

    ,(e) repeating steps (b) to (d) until a stopping condition is achieved whereby the location of the gas leak is indicated by the location of the sensor array,wherein determining the local gas concentration profile comprises calculating a gas concentration gradient.
