Determining the Antifungal Agent Clioquinol by HPLC, the Not So Pure Preparation: A Laboratory-Based Case Study for an Instrumental Analytical Chemistry Course
Autor: Peter M. Schaber, Geoffrey Hobika
Publikováno v: Journal of Chemical Education. 95:445-450
The case study approach provides students with a better appreciation of how scientists solve problems and conduct themselves in the “real world”. When applied to the undergraduate chemistry laboratory, this approach also challenges critical think

Application of californium-252 plasma desorption mass spectroscopy to chlorophyll studies
Autor: T. J. Michalski, Ralph C. Dougherty, Jerry E. Hunt, Peter M. Schaber, Joseph J. Katz
Publikováno v: International Journal of Mass Spectrometry and Ion Physics. 53:45-48
Applications of 252Cf-PDMS to a variety of chlorophyll problems are described. This form of heavy particle induced desorption mass spectroscopy is highly suitable to the mass measurement of nonvolatile, thermally unstable chlorophylIs and chlorophyll

High-performance liquid chromatographic study of the chlorophyll allomerization reaction
Autor: Jerry E. Hunt, Peter M. Schaber, Richard Fries, Joseph J. Katz
Publikováno v: Journal of Chromatography A. 316:25-41
The allomerization of chlorophyll has been investigated by reversed-phase HPLC. Four major product peaks (two sets of doublets) are observed in the HPLC chromatogram. These are shown to be pairs of stereoisomers of two major components. Similar resul
