PCT No. PCT/GB95/00269 Sec. 371 Date Oct. 15, 1996 Sec. 102(e) Date Oct. 15, 1996 PCT Filed Feb. 10, 1995 PCT Pub. No. WO95/22052 PCT Pub. Date Aug. 17, 1995A device (10) is disclosed for measuring the concentration of metal ions in solution, particularly lead in blood. The device comprises a mercury free electrode (16), which is separated from the test solution (21) by a layer of material (20) which permits passage therethrough of the ions to be measured. In preferred embodiments an insulating layer (18) having an array of photoablated holes (19) is disposed between the electrode and the ion-permeable layer (20). Also disclosed are methods for operating the device and measuring ion concentration using anodic stripping voltametry, and assay kits incorporating devices as described together with appropriate meters and circuitry.
