Abstract
A shim for use in defining a fluid passage in a particle detecting fluid cell has a base portion of metal and head portion, defining the fluid passage, which haws a metal core and a covering which is non-corrodible by water and acid. The sides of the covering and the base portion define continuous flat surfaces which are sandwiched between plates defining the other boundaries of the flow passage. The coverings form a fluid tight seal with the plates and the base portions of the shims bear the compressive forces exerted on the shims by the plates.
