Abstract:
An on-demand vapour generator includes a vapour chamber configured to produce a vapour and a vapour absorption assembly configured to receive flows of vapour from the vapour chamber. The vapour absorption assembly includes a first vapour-permeable passage having a passage outlet and at least one second vapour-permeable passage that is closed. When vapour absorption assembly receives a flow of vapour from the vapour chamber, the flow of vapour passes through the first vapour-permeable passage to the passage outlet at least substantially without absorption of vapour from the flow of vapour. However, when a flow of vapour is not received from the vapour chamber, vapour entering the vapour absorption assembly from the vapour chamber passes into the first vapour-permeable passage and the at least one second vapour-permeable passage and is at least substantially absorbed.

Claim (Index 1):
A vapour generator for a detection apparatus, the generator comprising:\n a vapour source coupled by a flow path to provide vapour through an impeder to an outlet for dispensing vapour to the detection apparatus, wherein the impeder comprises:\n a first vapour permeable passage arranged to impede diffusion of the vapour from the source to the outlet and to enable vapour to be driven from the source to the outlet, the first vapour permeable passage being in fluid communication with the source, via the flow path, and with the outlet for dispensing vapour to the detection apparatus, and \n a sink separated from the outlet by the first vapour permeable passage wherein the sink comprises a material adapted to take up the vapour and is arranged to divert diffusion of vapour away from the outlet, the first vapour permeable passage and the sink arranged so that, in response to a pressure difference between the outlet and the vapour source, resistance to driving vapour flow through the first vapour permeable passage to the outlet is less than the resistance to driving vapour flow into the sink.
