“…Wieme 1 and Issaq et al 2 believed that µ eo ≈kI -0.5 , where k and following a, b, a', b' are all constants of their equations. Salomon et al 3 and Morris et al 4 believed that µ eo ＝b/(1+aI 0.5 ) and Legoux et al 5 confirmed it by the paper electrophoresis. In CE, CEC and microfluidic chip analysis, the ionic strength is not very high.…”

It was believed that electroosmotic mobility µ eo is inversely proportional to the square root of the ionic strength I. But the linear relationship for regression analysis was expressed differently in different papers. The paper studied the linear expression of the mathematical relationship between µ eo and c (background buffer concentration) by mathematical transform and real experimental data. µ eo values of fused silica capillary were determined in four buffer systems. Their experimental conditions were controlled carefully for decreasing temperature difference ∆T and pH difference ∆pH in 50 µm ID capillary, in which no double layer overlap existed. The linear relationship between the reciprocal of electroosmotic mobility and the square root of concentration (or ionic strength) was derived by mathematical method. The regression analysis of experimental data was shown to well correspond to the relationship. The constants in regression equation could be well defined and the calculated results were acceptable.

“…Salomon (49) conjectured that the addition of methanol to the electrolyte solution does not affect the surface charge equilibrium, but does increase the number of ionized silanol groups on the capillary wall by shielding the charged ions from each other, thus, allowing more ions to exist in a given area. This should increase the zeta potential and thus EOF.…”

“…There are several experimental parameters which may be modified to accomplish this. Several reviews have been published which describe the effects of these parameters on EOF (47)(48)(49)(50)(51)(52) Temperature control is now available in many commercial CE instruments. This control is necessary in part because of the effect of temperature on EOF.…”

Thus, some thesis and dissertation copies are in typewriter face, while others may be from any type of computer printer.The quality of this reproduction is dependent upon the quality of the copy submitted. Broken or indistinct print, colored or poor quality illustrations and photographs, print bleedthrough, substandard margins, and improper alignment can adversely affect reproduction.In the unlikely event that the author did not send UMI a complete manuscript and there are missing pages, these will be noted. Also, if unauthorized copyright material had to be removed, a note will indicate the deletion.Oversize materials (e.g., maps, drawings, charts) are reproduced by sectioning the original, beginning at the upper left-hand comer and continuing from left to right in equal sections with small overlaps. Each original is also photographed in one exposure and is included in reduced form at the back of the book.
