Linear-sweep voltammograms of 10 mM H2O2 in 0.1 M phosphate buffer (pH 7.4) at the various electrodes were obtained; at Pt loading levels 150 &micro;g cm-2 the Pt - Nafion - vitreous carbon electrode showed a higher response than the Pt electrode. An application of the cited electrode to the flow injection analysis - electrochemical detection of H2O2 is described. Generally the rectilinear working range was from 1 &micro;M to ~50 mM H2O2.',

The electrode was incorporated in a flow injection system containing a large-volume wall-jet detector with a Ag - AgCl reference electrode. The electrode exhibited better stability and selectivity than did a solid Pt electrode, and showed comparable sensitivity. The calibration graph was rectilinear up to 30 mM glucose.

			'abstract' => 'The selectivity and analytical application of a thin-layer electrochemical detector comprised of glassy carbon electrode coated with Nafion film were investigated. As a result of the ion-exchange characteristics of the Nafion polymer, the selectivity and stability were improved greatly. The coated electrode has a good response only for cations with the same sensitivity as an uncoated (bare) electrode, but not for anions, and the response for neutral molecules is decreased three-fold. The diffusion of electroactive compounds in Nafion film is discussed based on the results of flow injection experiments. The peak current at the coated electrode was independent of the flow-rate of the mobile phase. Electrode poisoning due to protein adsorption was minimized. The use of 30% methanol or 10% acetonitrile in the mobile phase did not affect the performance of the coated electrode. Various analytes having three kinds of charge state, i.e., anionic, cationic and neutral, were tested. Liquid chromatography with electrochemical detection of ascorbic acid, norepinephrine, epinephrine, dopamine and uric acid was demonstrated.',

An expression is given for the limiting current of an amperometric device in response to an analyte in the presence of an interfering species. Experiments were carried out with a Pt electrode, modified with glucose oxidase by electropolymerization from 0.2 M acetate buffer of pH 5.2 containing o-phenylenediamine or coated with Nafion/glucose oxidase solution in phosphate buffer of pH 7.4, and with glucose oxidase incorporated into a C paste electrode containing Ru or 2-methyl-1,4-naphthoquinone. Pt electrodes, bare and coated with 2 or 5% Nafion, were also evaluated. The enzyme-free electrodes were used for monitoring dopamine with ascorbic acid, 3,4-dihydroxyphenylacetic acid and adrenaline by FIA and chronoamperometry; the Nafion-coated electrodes showed good selectivity relative to the first two compounds. The enzyme electrodes were used to monitor glucose in the presence of ascorbic acid, uric acid, paracetamol, catechol and dopamine by FIA. The Pt/Nafion/enzyme electrode showed the best selectivity. The validity of the theoretical approach was confirmed.',

The electrode was incorporated in a flow injection system containing a large-volume wall-jet detector with a Ag - AgCl reference electrode. The electrode exhibited better stability and selectivity than did a solid Pt electrode, and showed comparable sensitivity. The calibration graph was rectilinear up to 30 mM glucose.

			'abstract' => 'The selectivity and analytical application of a thin-layer electrochemical detector comprised of glassy carbon electrode coated with Nafion film were investigated. As a result of the ion-exchange characteristics of the Nafion polymer, the selectivity and stability were improved greatly. The coated electrode has a good response only for cations with the same sensitivity as an uncoated (bare) electrode, but not for anions, and the response for neutral molecules is decreased three-fold. The diffusion of electroactive compounds in Nafion film is discussed based on the results of flow injection experiments. The peak current at the coated electrode was independent of the flow-rate of the mobile phase. Electrode poisoning due to protein adsorption was minimized. The use of 30% methanol or 10% acetonitrile in the mobile phase did not affect the performance of the coated electrode. Various analytes having three kinds of charge state, i.e., anionic, cationic and neutral, were tested. Liquid chromatography with electrochemical detection of ascorbic acid, norepinephrine, epinephrine, dopamine and uric acid was demonstrated.',

An expression is given for the limiting current of an amperometric device in response to an analyte in the presence of an interfering species. Experiments were carried out with a Pt electrode, modified with glucose oxidase by electropolymerization from 0.2 M acetate buffer of pH 5.2 containing o-phenylenediamine or coated with Nafion/glucose oxidase solution in phosphate buffer of pH 7.4, and with glucose oxidase incorporated into a C paste electrode containing Ru or 2-methyl-1,4-naphthoquinone. Pt electrodes, bare and coated with 2 or 5% Nafion, were also evaluated. The enzyme-free electrodes were used for monitoring dopamine with ascorbic acid, 3,4-dihydroxyphenylacetic acid and adrenaline by FIA and chronoamperometry; the Nafion-coated electrodes showed good selectivity relative to the first two compounds. The enzyme electrodes were used to monitor glucose in the presence of ascorbic acid, uric acid, paracetamol, catechol and dopamine by FIA. The Pt/Nafion/enzyme electrode showed the best selectivity. The validity of the theoretical approach was confirmed.',

			'abstract' => 'The selectivity and analytical application of a thin-layer electrochemical detector comprised of glassy carbon electrode coated with Nafion film were investigated. As a result of the ion-exchange characteristics of the Nafion polymer, the selectivity and stability were improved greatly. The coated electrode has a good response only for cations with the same sensitivity as an uncoated (bare) electrode, but not for anions, and the response for neutral molecules is decreased three-fold. The diffusion of electroactive compounds in Nafion film is discussed based on the results of flow injection experiments. The peak current at the coated electrode was independent of the flow-rate of the mobile phase. Electrode poisoning due to protein adsorption was minimized. The use of 30% methanol or 10% acetonitrile in the mobile phase did not affect the performance of the coated electrode. Various analytes having three kinds of charge state, i.e., anionic, cationic and neutral, were tested. Liquid chromatography with electrochemical detection of ascorbic acid, norepinephrine, epinephrine, dopamine and uric acid was demonstrated.',

An expression is given for the limiting current of an amperometric device in response to an analyte in the presence of an interfering species. Experiments were carried out with a Pt electrode, modified with glucose oxidase by electropolymerization from 0.2 M acetate buffer of pH 5.2 containing o-phenylenediamine or coated with Nafion/glucose oxidase solution in phosphate buffer of pH 7.4, and with glucose oxidase incorporated into a C paste electrode containing Ru or 2-methyl-1,4-naphthoquinone. Pt electrodes, bare and coated with 2 or 5% Nafion, were also evaluated. The enzyme-free electrodes were used for monitoring dopamine with ascorbic acid, 3,4-dihydroxyphenylacetic acid and adrenaline by FIA and chronoamperometry; the Nafion-coated electrodes showed good selectivity relative to the first two compounds. The enzyme electrodes were used to monitor glucose in the presence of ascorbic acid, uric acid, paracetamol, catechol and dopamine by FIA. The Pt/Nafion/enzyme electrode showed the best selectivity. The validity of the theoretical approach was confirmed.',

Linear-sweep voltammograms of 10 mM H2O2 in 0.1 M phosphate buffer (pH 7.4) at the various electrodes were obtained; at Pt loading levels 150 &micro;g cm-2 the Pt - Nafion - vitreous carbon electrode showed a higher response than the Pt electrode.

	'abstract' => 'The selectivity and analytical application of a thin-layer electrochemical detector comprised of glassy carbon electrode coated with Nafion film were investigated. As a result of the ion-exchange characteristics of the Nafion polymer, the selectivity and stability were improved greatly. The coated electrode has a good response only for cations with the same sensitivity as an uncoated (bare) electrode, but not for anions, and the response for neutral molecules is decreased three-fold. The diffusion of electroactive compounds in Nafion film is discussed based on the results of flow injection experiments. The peak current at the coated electrode was independent of the flow-rate of the mobile phase. Electrode poisoning due to protein adsorption was minimized. The use of 30% methanol or 10% acetonitrile in the mobile phase did not affect the performance of the coated electrode. Various analytes having three kinds of charge state, i.e., anionic, cationic and neutral, were tested. Liquid chromatography with electrochemical detection of ascorbic acid, norepinephrine, epinephrine, dopamine and uric acid was demonstrated.',

			'abstract' => 'A generalized method is presented for assessing the extent of interference by foreign species in amperometric determination of an analyte. An expression is given for the limiting current of an amperometric device in response to an analyte in the presence of an interfering species. Experiments were carried out with a Pt electrode, modified with glucose oxidase by electropolymerization from 0.2 M acetate buffer of pH 5.2 containing o-phenylenediamine or coated with Nafion/glucose oxidase solution in phosphate buffer of pH 7.4, and with glucose oxidase incorporated into a C paste electrode containing Ru or 2-methyl-1,4-naphthoquinone. Pt electrodes, bare and coated with 2 or 5% Nafion, were also evaluated. The enzyme-free electrodes were used for monitoring dopamine with ascorbic acid, 3,4-dihydroxyphenylacetic acid and adrenaline by FIA and chronoamperometry; the Nafion-coated electrodes showed good selectivity relative to the first two compounds. The enzyme electrodes were used to monitor glucose in the presence of ascorbic acid, uric acid, paracetamol, catechol and dopamine by FIA. The Pt/Nafion/enzyme electrode showed the best selectivity. The validity of the theoretical approach was confirmed.',

Compared with Pt, vitreous carbon and Pt-modified vitreous carbon electrodes, the Nafion - vitreous carbon system displayed increased stability. Linear-sweep voltammograms of 10 mM H2O2 in 0.1 M phosphate buffer (pH 7.4) at the various electrodes were obtained; at Pt loading levels 150 &micro;g cm-2 the Pt - Nafion - vitreous carbon electrode showed a higher response than the Pt electrode. An application of the cited electrode to the flow injection analysis - electrochemical detection of H2O2 is described. Generally the rectilinear working range was from 1 &micro;M to ~50 mM H2O2.',

			'abstract' => 'A Nafion film was coated on an electrochemically pre-treated vitreous-carbon electrode, and Pt particles were deposited on the film by potential cycling between +0.7 and -0.15 V. Glucose oxidase was subsequently immobilized on the electrode with use of bovine serum albumin and glutaraldehyde and covered with a polycarbonate membrane. The electrode was incorporated in a flow injection system containing a large-volume wall-jet detector with a Ag - AgCl reference electrode. The electrode exhibited better stability and selectivity than did a solid Pt electrode, and showed comparable sensitivity. The calibration graph was rectilinear up to 30 mM glucose. The electrode was applied to determine glucose in blood; results agreed with those obtained with a Boehringer Refolux monitor.',

			'abstract' => 'The selectivity and analytical application of a thin-layer electrochemical detector comprised of glassy carbon electrode coated with Nafion film were investigated. As a result of the ion-exchange characteristics of the Nafion polymer, the selectivity and stability were improved greatly. The coated electrode has a good response only for cations with the same sensitivity as an uncoated (bare) electrode, but not for anions, and the response for neutral molecules is decreased three-fold. The diffusion of electroactive compounds in Nafion film is discussed based on the results of flow injection experiments. The peak current at the coated electrode was independent of the flow-rate of the mobile phase. Electrode poisoning due to protein adsorption was minimized. The use of 30% methanol or 10% acetonitrile in the mobile phase did not affect the performance of the coated electrode. Various analytes having three kinds of charge state, i.e., anionic, cationic and neutral, were tested. Liquid chromatography with electrochemical detection of ascorbic acid, norepinephrine, epinephrine, dopamine and uric acid was demonstrated.',
