Planar electrochemical microcells were micro-machined in a microcrystalline boron-doped diamond (BDD) thin layer using a femtosecond laser. The electrochemical performances of the new laser-machined BDD microcell were assessed by differential pulse anodic stripping voltammetry (DPASV) determinations, at the nanomolar level, of the four heavy metal ...

A differential pair of planar thin-film interdigitated electrodes, deposited on a ceramic pad, was used as a conductometric transducer. The three-enzyme system (invertase, mutarotase, glucose oxidase), immobilized on the transducer surface, was used as a bioselective element. The ratio between enzymes in the membrane was found experimentally consid...

Both new guidelines concerning elemental impurity limit concentrations and novel analytical procedures for elemental analysis of pharmaceutical substances are being adopted by the United States Pharmacopeia (USP). This paper outlines the optimization of two sample preparation procedures for organic pharmaceutical excipient products, one relying on ...
