The Global ETD Search service is a free service for researchers
to find electronic theses and dissertations. This service is
provided by the
Networked Digital Library of Theses and Dissertations.
Our metadata is collected from universities around the world. If you manage a university/consortium/country archive and want to be added, details can be found on the NDLTD website.

Ion interaction liquid chromatography : energetics, mechanism and gradient design considerations for the assay of serum thyroid hormonesBedard, Pierre R. January 1985 (has links)
The competition between two molecules of similar polarity for adsorption sites on the stationary phase is discussed in light of rapid kinetics of adsorption and desorption, and of the effects of temperature, acetonitrile, surfactant (cyclohexylaminopropane sulfonic acid, CAPS) and salt concentrations on the retention of the thyroid hormones (3,5-diiodothyronine, T2; 3,3',5-triiodothyronine, T3 and thyroxine, T4). A three parameter equation relates the surfactant concentration and ionic strength to the retention of the hormones and is analyzed in terms of the Stern-Gouy-Chapman theory. A second order polynomial describes the temperature dependency and permits the evaluation of the enthalpy, entropy and heat capacity, demonstrating a reduction in the molecular motion of the analyte with increasing surfactant and acetonitrile concentrations. The equation parameters for linear or non-linear equations, using data sets with or without homogeneous variances, are evaluated using a Simplex optimization procedure that uses one of two proposed optimization criteria. The construction and operation of a computer based gradient programmer for HPLC is described. A surfactant mediated gradient elution with electrochemical detection is examined for the analysis of serum thyroid hormones.
