Blase, Ryan Christopher (2012-02-14)Drift tube ion mobility spectrometry (IMS) is a powerful, post-ionization separation that yields structural information of ions through an ion-neutral collision cross section. The ion-neutral collision cross section is ...
-
Salinas, Silvia Adriana (Texas A&M University, 2004-09-30)Gas phase chemiluminescence nitrogen specific detector (CLND)is used for the direct analysis of underivatized nitrogen-containing components such as alkylamines that can not be detected by the so called universal HPLC ...
-
Zinnel, Nathanael (2014-04-25)Mass spectrometry (MS) has been established as important analytical tool in the characterization of an array of analyte classes, including biological samples. However, without hyphenation with other techniques, the approach ...

Vigh, Gyula; Rawjee, Yasir Y.; Williams, Robert L., Jr. (United States. Patent and Trademark Office; Texas A&M University. Libraries, 1997-03-25)The invention concerns electrophoresis and methods and electrolyte compositions for decoupling or isolating the dual functions of the electrolyte composition in order to increase separation selectivity or reduce electromigration ...
-
Javier, Alnald Caintic (2013-08-05)Computational techniques based on density functional theory (DFT) and experimental methods based on electrochemistry (EC), electrochemical scanning tunneling microscopy (EC-STM), and high-resolution electron energy loss ...
-
Cummins, Kyle (2012-07-16)A pair of studies investigating the deposition and surface chemical properties of ultrathin metal films were pursued: (i) Pt-Co alloys on Mo(110); and (ii) Pd on Pt(111). Experimental measurement was based on a combination ...
-
Sawyer, Holly Ann (Texas A&M University, 2006-04-12)Ion mobility-mass spectrometry (IM-MS), gas-phase hydrogen/deuterium (H/D) exchange ion molecule reactions and molecular modeling provide complimentary information and are used here for the characterization of peptide ion ...
-
Tao, Lei (2011-08-08)IM-MS is a 2-D technique which provides separations based on ion shape (ion-neutral collision cross-section, Ω) and mass (m/z ratio). Ion structures can be deduced from the measured collision cross-section (Ωmeas) by ...
-
Chen, Xiaojia (2009-05-15)Invented in the 1950s, gel electrophoresis has now become a routine analytical method to verify the size of nucleic acids and proteins in molecular biology labs. Conventional gel electrophoresis can successfully separate ...
-
Penner, Reginald Mark (Texas A&M University. Libraries, 1987)Fundamental and applied aspects of ion transport in polypyrrole films are investigated. In this context, three objectives have been accomplished: i) Composites of polypyrrole and a porous host membrane have been prepared ...
-
Cologna, Stephanie Marie (2012-02-14)Mass spectrometry (MS) has played a major role in the proteomic analysis of an array of biological samples. Even so, inherent limitations exist such as sample complexity and the dynamic range. In an attempt to overcome ...
-
North, Robert Yates (2011-08-08)Isoelectric trapping (IET) has become an accepted preparative-scale electrophoretic separation technique. However, there are still a number of shortcomings that limit its utility. The performance of the current ...
