A semi-volatile particulate matter detection device is disclosed for detecting semi-volatile particulate matter in a gas flow. The device has a first filter stage for receiving the gas flow, the first filter stage being configured to capture particulate matter and to be heated to a temperature of at least 150° C. to volatilise semi-volatile particulate matter to produce semi-volatile vapour for passing through the first filter stage with the gas flow. The device also has a conveyance section downstream of the first filter stage to convey the gas flow and the semi-volatile vapour. A second filter stage is configured to receive the flow from the conveyance section. The temperature of the conveyance section and/or of the second filter stage is controllable so as to cause condensation of at least some of the semi-volatile vapour and collect it on the second filter stage. A detector is provided for detecting at least one characteristic of the condensed semi-volatile vapour on the second filter stage.
