This paper derives and analyzes the s-domain linear and time domain nonlinear models for a C-band wide locking range injection locked voltage controlled oscillator (ILVCO). Van der Pol equation is conducted to describe the behavior of ILVCO with different injection frequencies. Three phase plane plots, that are free-run, injection locked, and chaos states,(More)
We report the separation of polycyclic aromatic hydrocarbons (PAHs) using 0.1% poly(ethylene oxide) (PEO) in micellar electrokinetic chromatography (MEKC). In the presence of PEO, adsorption of PAHs on the capillary wall was reduced, leading to better resolution and reproducibility. Effects of tetrapentylammonium iodide (TPAI), dextran sulfate (DS),(More)
Separations of small ions were carried out under nonequilibrated conditions using capillaries treated with NaOH, HCl, or tris(hydroxymethyl)aminomethane (Tris) prior to analysis. For separations of benzoic acid isomers or acids and amines under weakly acidic conditions, capillaries flushed with 0.1 M NaOH and subsequently with running buffers prior to(More)
