Analyses of mixtures of three amino acids, alanine, glycine, and valine, are used to determine optimal measurement conditions. Sensitivity increases of as much as a factor of 3 are achieved, at the expense of some loss in chromatographic resolution, by use of an 80-\u03bcL NMR cell, Instead of a smaller 14-\u03bcL cell. Analysis of the antimycin A mixture, using the optimal analytical high performance liquid chromatography/nuclear magnetic resonance conditions, reveals it to consist of at least 10 closely related components.", "description": "5 p.", "publisher": { "@type": "Organization", "name": "ACS Publications" }, "author": [ { "@type": "Person", "name": "Abidi, Sharon L.", "givenName": "Sharon L.", "familyName": "Abidi" }, { "@type": "Person", "name": "Wilkins, Charles L.", "givenName": "Charles L.", "familyName": "Wilkins" }, { "@type": "Person", "name": "Ha, Steven T.
