The emanation device comprises: a housing 2, a passive delivery mechanism (12, Fig. 3) and a powered emanation means 6, wherein the housing is arranged to support the passive delivery mechanism in spatial arrangement over the emanation means. The passive delivery mechanism comprises a volatile liquid reservoir 4, one or more capillary tubes 7 in non-valved fluid communication with the reservoir at-one end thereof and a nozzle 8 located at the end of each capillary tube(s) remote from the reservoir, wherein each nozzle is in non-valved fluid communication with each capillary tube(s). Preferably, the emanation means is a heater or an ultrasonic transducer. A method of providing a flow rate of volatile liquid between 0.1-500 mL/hr onto the emanation means is also claimed. |
