Download or read book The Distribution of Organic Bases in Reverse Phase Liquid Chromatography written by Dudley Shelton Jayasinghe and published by . This book was released on 1989 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: The distribution of hydrophobic ionogenic organic compounds (HIOC's) between aqueous and nonaqueous phases has been investigated. The HIOC's are aniline and methyl substituted anilines. The aqueous phases are methanol-water mixed solvents with varying pH and ionic strength. The nonaqueous phases are silica and alkyl derivatized silica with ethyl- (C-2), octyl- (C-8), and octadecyl- (C-18) silanes. A gas-liquid equilibration method has been developed to determine the Henry's law constants and the activity coefficients of methyl anilines in methanol-water mixed solvents. The logarithm of the Henry's law constants vary quadratically with the volume fraction of methanol. The chromatographic study has been performed to investigate the effect of three mobile phase factors, fraction of methanol, pH, and ionic strength, on the retention of methyl anilines on different stationary phases. The logarithm of mass distribution ratios, log k's, of methyl anilines vary linearly with the volume fraction of methanol. The ratios of H / k' of methyl anilines increase with increase in methanol in the mobile phase, indicating an increase in the activity coefficients in the stationary phases. This observation is found to be true for different methyl anilines in different stationary phases. A partition model is presented to describe the effect of pH and ionic strength on the retention of HIOC's in the mobile phase. The variation in log k' among neutral and ionic methyl anilines can be explained by linear free energy relationships. Equations are established to predict retention of neutral or ionized methyl anilines from their octanol-water partition coefficients at any methanol content in the mobile phase. Acid dissociation constants of methyl anilines determined from the dependence of log k' on pH are in close agrement with those determined by potentiometric titrations. The effect of ionic strength on the retention of both neutral and ionic species of methyl anilines is negligible. That is, the contribution from electrostatic energy and salting out effect are not significant. The chromatographic study is extended to study the retention of methyl anilines on silica as a function of pH and methanol at a constant ionic strength. The dependence of retention on pH is qualitatively interpreted from an ion exchange reaction between the dissociated silanol groups in the surface and the ionized methyl anilines. The effect of methanol on the retention of methyl anilines and of pyridine on silica is described by a quadratic relationship between the log k' and volume fraction of methanol.

Download or read book Protein Liquid Chromatography written by M. Kastner and published by Elsevier. This book was released on 2000 with total page 978 pages. Available in PDF, EPUB and Kindle. Book excerpt: Protein Liquid Chromatography is a handbook-style guide to liquid chromatography as a tool for isolating and purifying proteins, consisting of 25 individual chapters divided into three parts: Part A covers commonly-used, classic modes of chromatography such as ion-exchange, size-exclusion, and reversed-phase; Part B deals with various target protein classes such as membrane proteins, recombinant proteins, and glycoproteins; and Part C looks at various miscellaneous related topics, including coupling reaction, buffer solution additives, and software. The text as a whole can be viewed as a systematic survey of available methods and how best to use them, but also attempts to provide an exhaustive coverage of each facet. How to solve a specific problem using a chosen method is the overall essence of the volume. The principle philosophy of this compilation is that practical application is everything; therefore, both classical and modern methods are presented in detail, with examples involving conventional, medium- and high-pressure techniques. Over-exposure to history, concept, and theory has deliberately been avoided. The reader will find a wealth of tips and tricks from users for users, including advice on the advantages and disadvantages of each method. Easy-to-read sections on "Getting started now" and "Where to go from here" attempt to provide hands-on, fool-proof detailed practical procedures with complete and even standard model runs for any scientist or technician at work in this area.
