Beschreibung
Zusammenfassung:	Improved preconcentrators, particularly MEMs scale preconcentrators which possess a coating comprising polymers of intrinsic microporosity (PIMs). There is further provided devices comprising the preconcentrator, and methods of preparation and use. There is particular benefit directed to the use of a MEMs scale heater coated with the PIMs for use in hand-held or field portable chemical detection devices. The polymer of intrinsic microporosity comprises a polymer, with a monomer repeat unit of Formula I wherein A is one or more optionally substituted aryl, heterocyclic, cycloalkyl or bicycloalkyl rings, is greater than 5, preferably 5 to 10000, and X may be selected from CH, CH2, 0, S, N or NH.
