摘要： A probe device for use in measuring trace quantities of a component in a liquid environment comprises: (i) a membrane (2) which is permeable to the component; and (ii) a layer of a material (4) capable of binding the component and arranged to receive material which has permeated through the membrane (2) from a face (6) thereof juxtaposed to the fluid environment. The membrane (2) may for example be a polyacrylamide gel and the material (4) an ion exchange resin. The device may be used, for example, for determining quantities of trace metals in an aqueous environment.
