Flame ionization detection of hydrocyanic acid ; Analysis of trace aqueous solutions

Creator:: Claeys, Robert Raymond
Abstract:: A gas chromatographic procedure was developed for the determination of nanogram quantities of hydrocyanic acid using a flame ionization detector. Excellent chromatograms were obtained on a porous polyaromatic polymer column (Porapak Q) at 60°C. The procedure was employed for the analysis of HCN in aqueous cyanide solutions. Solutions as low...

Direct-sampling optical techniques for the study of transient combustion events

Creator:: Herron, John R.
Abstract:: Techniques have been developed for measuring the temperature, stable species concentrations, and atomic radical concentrations during a transient combustion event. They combine the features of direct sampling with two spectroscopic techniques to produce relatively simple diagnostic techniques to obtain time-resolved measurements. In this study, a transient event was provided by...

Quantification of Trace Volatile Sulfur Compounds in Milk by Solid-Phase Microextraction and Gas Chromatography–Pulsed Flame Photometric Detection

Creator:: Vazquez-Landaverde, P. A., Torres, J. A., and Qian, M. C.
Abstract:: Volatile sulfur compounds have been reported to be responsible for the sulfurous off-flavors generated during the thermal processing of milk; however, their analysis has been a challenge due to their high reactivity, high volatility, and low sensory threshold. In this study, reactive thiols were stabilized and the volatile sulfur compounds...

Glass capillary gas chromatographic analysis for trace amounts of cyclopropenoid fatty acids

Creator:: Ryan, Daberath
Abstract:: Dietary cyclopropenoid fatty acids (CPFA) have long been known to cause pronounced physiological disorders in both farm and laboratory animals. Past work has shown CPFA to be a powerful promoter of carcinogenesis in trout, rats and mice. Sterculic and malvalic acids (CPFA's) are found in seed lipids of plants from...

Zero kinetic energy photoelectron spectroscopy of polycyclic aromatic hydrocarbons

Creator:: Zhang, Jie
Abstract:: In this dissertation, I present electronic spectra of a few polycyclic aromatic hydrocarbons (PAHs): tetracene, pentacene, pyrene, benzo[g,h,i]perylene and benzo[a]pyrene using resonantly enhanced multiphoton ionization (REMPI) and zero kinetic energy (ZEKE) photoelectron spectroscopy. The work of tetracene and pentacene also combine a laser desorption source with a ZEKE spectrometer, demonstrating...

Evaluating the Toxicity of Organophosphate Flame Retardants in Zebrafish

Creator:: Britsch, Kimberly A.
Abstract:: Flame retardants are in many home products including couches, chairs, and electronics. The most commonly used flame retardants contained polybrominated diphenyl ethers (PBDEs) until 2004, when the majority of these chemicals were phased out. PBDEs were found to be persistent, bioaccumulative, and toxic to both humans and the environment. Organophosphate...
