Abstract: There is provided a gas sensing apparatus (30) for sensing one or more analytes in a gas or gas mixture. The gas sensing apparatus (30) comprises: a plurality of sensors (32), each sensor (32) including a polymer layer (42), each polymer layer (42) made of a respective different type of chemically non-selective or semi-selective polymer; and a measurement device (38) configured to measure a change in parameter of each sensor (32) responsive to interaction of an analyte with the respective polymer layer (42).
