Title
(EN) Molecular sieves
Abstract
(EN)

A molecular sieve (20) for an IMS is formed of a solid block (24) of zeolite within a closely fitting housing (21). The block (24) has multiple passages (25) to (28) through which gas can flow along the block. The block (24) may be made by casting or extrusion and the sieve material may include a dopant.
