Using flow injection analysis, a 20 pmol mass detection limit was achieved using a 20 &micro;L injection volume. Cystine and SSC were shown to behave quite differently in this detection system. The signal from cystine displayed a dependence on flow rate reflective of simple mass transfer, while the signal from SSC was more sensitive to mobile phase flow rate. The cystine signal was insensitive to pH, while SSC's signal depended significantly on pH. The SSC reduction reaction at the upstream Au + Hg electrode was determined by cyclic voltammetry to be RSSO3- + 2H(+) + 2e(-) --> RSH + HSO3-. The signal monitored at the downstream electrode was attributed mainly to the oxidation of Hg to Hg cysteinate below pH 4. Both cysteine and bisulfite contributed to the detection signal above pH 4.5. The optimum pH for the detection of SSC was approximately 5.2. (C) 1997 Elsevier Science S.A. 22 References',

Each compound gave a response in a BAS LC4A electrochemical system, incorporating a mercury-coated gold electrode at -1.75 V, when 0.1 M tetrabutylammonium tetrafluoroborate (I) was added to the solvent as carrier electrolyte; calibration graphs were rectilinear and the sensitivity was 200 ng per injection. However, none of the steroids was retained on the column in the presence of I. The method should be applicable in flow injection analysis, or with post-column addition of electrolyte.',

Abstract: Square-wave voltammetry was used in a flow injection system for detection of electroactive species. A Kalman filter was an effective aid in the separation of closely overlapping responses. A standard-additions graph for dopamine in 0.28 M H2SO4 was obtained and the peak responses were rectilinearly related to concentration. The voltammetric responses of Pb(II) and TlI in 0.9 M HNO3 on working electrodes of mercury on gold and mercury on vitreous carbon were also rectilinearly related to concentration.

Abstract: The dual gold + mercury (Au + Hg) amalgam electrode was found to be an effective detector for S-sulfocysteine (SSC). Using flow injection analysis, a 20 pmol mass detection limit was achieved using a 20 µL injection volume. Cystine and SSC were shown to behave quite differently in this detection system. The signal from cystine displayed a dependence on flow rate reflective of simple mass transfer, while the signal from SSC was more sensitive to mobile phase flow rate. The cystine signal was insensitive to pH, while SSC's signal depended significantly on pH. The SSC reduction reaction at the upstream Au + Hg electrode was determined by cyclic voltammetry to be RSSO3- + 2H(+) + 2e(-) --> RSH + HSO3-. The signal monitored at the downstream electrode was attributed mainly to the oxidation of Hg to Hg cysteinate below pH 4. Both cysteine and bisulfite contributed to the detection signal above pH 4.5. The optimum pH for the detection of SSC was approximately 5.2. (C) 1997 Elsevier Science S.A. 22 References

A Kalman filter was an effective aid in the separation of closely overlapping responses. A standard-additions graph for dopamine in 0.28 M H2SO4 was obtained and the peak responses were rectilinearly related to concentration. The voltammetric responses of Pb(II) and TlI in 0.9 M HNO3 on working electrodes of mercury on gold and mercury on vitreous carbon were also rectilinearly related to concentration.',

			'abstract' => 'The dual gold + mercury (Au + Hg) amalgam electrode was found to be an effective detector for S-sulfocysteine (SSC). Using flow injection analysis, a 20 pmol mass detection limit was achieved using a 20 &micro;L injection volume. Cystine and SSC were shown to behave quite differently in this detection system. The signal from cystine displayed a dependence on flow rate reflective of simple mass transfer, while the signal from SSC was more sensitive to mobile phase flow rate. The cystine signal was insensitive to pH, while SSC's signal depended significantly on pH. The SSC reduction reaction at the upstream Au + Hg electrode was determined by cyclic voltammetry to be RSSO3- + 2H(+) + 2e(-) --> RSH + HSO3-. The signal monitored at the downstream electrode was attributed mainly to the oxidation of Hg to Hg cysteinate below pH 4. Both cysteine and bisulfite contributed to the detection signal above pH 4.5. The optimum pH for the detection of SSC was approximately 5.2. (C) 1997 Elsevier Science S.A. 22 References',

Abstract: Cortisone, hydrocortisone, prednisone, prednisolone, dexamethasone and betamethasone could be separated by HPLC on a 15-cm Hypersil (5 µm) column with methanol - 1,2-dichloroethane (3:197) as mobile phase (1.0 mL min-1). Each compound gave a response in a BAS LC4A electrochemical system, incorporating a mercury-coated gold electrode at -1.75 V, when 0.1 M tetrabutylammonium tetrafluoroborate (I) was added to the solvent as carrier electrolyte; calibration graphs were rectilinear and the sensitivity was 200 ng per injection. However, none of the steroids was retained on the column in the presence of I. The method should be applicable in flow injection analysis, or with post-column addition of electrolyte.
