Abstract
A vapor generator system () for an IMS () or other apparatus has a chamber () in which vapor is produced. A fan or other flow generator () is connected to an inlet () of the vapor chamber () and its outlet () is connected to an adsorbent passage (), such as formed by a bore through a block () of carbon. When the fan () is on gas flows through the vapor chamber () and the adsorbent passage () to the IMS () or other outlet, with little vapor being adsorbed in the passage. When the fan () is off, any vapor molecules that escape to the adsorbent passage () do so at a low rate such that substantially all is adsorbed and no vapor escapes.
