Enzyme Dual-Electrode for Analyte Determination
for Volatile Organic Compounds by Dynamic Headspace Concentration
2200
The advantages of a dual microband electrode for biochemical electroanalysis are discussed. Responses of electrodes with different interelectrode space are compared. In the generation-collection mode, glucose is detected up to a concentration of 8 mM. H. Allen O. Hill*, Naphthali A. Klein, Ioanna S. M. Psalti, and Nicholas J. Walton, Inorganic Chemistry Laboratory, South Parks Road, Oxford OX1 3QR, England Molecular Formula Determination of Capillary Column Gas Chromatographic Effluents Using Combined Microwave-Induced Plasma Emission and Mass Spectral Data 2207 The elemental responses of a set of small molecules are used to obtain the elemental ratios and composition of larger, structurally unrelated compounds. Combining this information with known molecular weights allows molecular formulae to be determined. D. B. Hooker and J.
