Abstract
An IMS system or the like has dopant contained in a way such that it is only released when needed. The dopant could be contained in a device () similar to an ink-jet printer and released as droplets () when required. Alternatively, the dopant could be trapped in material () of a molecular sieve () in such a way that it is not normally released into air flowing through the sieve but can be released by energising a heater () in the sieve.
