Journal ArticleDOI
Direct observation of epinephrine and norepinephrine cosecretion from individual adrenal medullary chromaffin cells
Edward L. Ciolkowski,Bruce R. Cooper,Jeffrey A. Jankowski,James W. Jorgenson,R. Mark Wightman +4 more
TL;DR: Cyclic voltammetry at Nafion-coated carbon fiber microclectrodes has been used to monitor directly the release of catecholamines from individual adrenal medullary chromaffin cells and to identify the released catechlamine as epinephrine or norepinephrine.
Journal ArticleDOI
A hybrid of exponential and gaussian functions as a simple model of asymmetric chromatographic peaks.
Kevin Lan,James W. Jorgenson +1 more
TL;DR: The EGH serves as a useful alternative to the exponentially modified Gaussian (EMG) for modeling slightly asymmetric peaks since the two models produce nearly the same profile at relatively low asymmetries.
Journal ArticleDOI
Effects of methanol-modified mobile phase on the separation of isotopically substituted compounds by micellar electrokinetic capillary chromatography
TL;DR: In this article, the role of methanol on the resolution of dansylated methylamine and methyld3-amine was examined by using micellar electrokinetic capillary chromatography (MECC) utilizing a 25mM sodium dodecylsulfate pseudostationary phase and a mobile phase containing 4.9 M methanols.
Journal ArticleDOI
Scanning on-column voltammetric detector for open-tubular liquid chromatography.
Journal ArticleDOI
Capillary zone electrophoresis for the determination of electrophoretic mobilities and diffusion coefficients of proteins
TL;DR: Capillary zone electrophoresis can be used to determine mobilities and diffusion coefficients for analytes as mentioned in this paper, where the analyte concentration does not overload the system and perturb the axial homogeneity of the electric field strength.
