Method development for qualification and quantification of cannabinoids and terpenes in extracts by Gas chromatography-mass spectrometry
(2016-07-19)
Cannabinoids are a class of chemical compounds that act on cannabinoid receptors in cells. These receptors have different kinds of ligands, including endocannabinoids (produced in the body by humans and animals), ...
Advances in Separation Methodologies: Fatty Acid, Fatty Amine, Water, and Ethanol Determination by Ionic Liquid Gas Chromatography and D-Amino Acid Evaluation in Mammalian Brain by Liquid Chromatography
(2016-08-15)
This dissertation focuses on two chromatographic techniques, gas chromatography (GC) and high performance liquid chromatography (HPLC). The goal of the GC work is to describe advances in separation methodologies focusing ...
DERIVATIZATION OF SMALL ACIDS TO ENHANCE SENSITIVITY IN GAS CHROMATOGRAPHY MASS SPECTROMETRY AND GAS CHROMATOGRAPHY VACUUM ULTRAVIOLET SPECTROSCOPY
(2016-08-12)
Disinfection by-products (DBPs) are a significant concern in drinking water quality. Haloacetic acids, which are generated from disinfection processes, are one of the major groups in disinfection by-products. Because they ...
NEW METHODS FOR DISCOVERY, FINGERPRINTING, AND ANALYSIS OF CANNABIS SATIVA NATURAL PRODUCTS
(2018-08-27)
Cannabis sativa is an herbaceous annual that has always been of great interest due to its uses in the manufacturing of textiles and cordage, as well as for its medicinal properties. The two main bioactive components of C. ...
Designing thermally stable ionic liquid stationary phases for gas chromatography and examining their structure-property relationships
(2018-11-30)
Ionic liquids are popular in diverse scientific applications because of their unique physicochemical properties. The physicochemical properties of ionic liquids can be “tuned” by the modification of their structural moieties. ...
THE EVALUATION OF ENVIRONMENTAL CONTAMINANTS USING STATIC HEADSPACE GAS CHROMATOGRAPHY MASS SPECTROMETRY, VACUUM ULTRAVIOLET DETECTION
(2021-05-13)
In analytical chemistry the term “headspace” refers to the vapor that forms above a sample (liquid or solid) in a closed container. Headspace (HS) sampling is the method to promote partition between volatile components ...
TARGETED AND UNTARGETED CHROMATOGRAPHY-MASS SPECTROMETRY METHODS FOR ALCOHOLIC BEVERAGE ANALYSIS
(2021-08-16)
There has been an increased interest in the “craft” alcohol industry in recent years. Contrary to larger corporations that focus on standardizing their recipes for mass production, these small, independent businesses can ...
ANALYSIS OF ISOTOPIC ISOMERS BY GAS CHROMATOGRAPHY AND MOLECULAR ROTATIONAL RESONANCE SPECTROSCOPY AND ENANTIOSELECTIVE METHOD DEVELOPMENT BY LIQUID CHROMATOGRAPHY
(2023-05-22)
This dissertation focuses on developing improved methods and a better understanding of gas and liquid chromatographic separation of isotopic isomers and enantiomers. The second and third chapters of this thesis discuss ...
