Book Description
Optimization of preparative nonlinear chromatography was carried out for the first time for a biomolecule mixture. Conventional wisdom on optimization, which roots from analytical chromatography, dictates optimizing resolution in an analytical column and obtaining similar separation in a large column for isolation. Such a method of optimization significantly under uses the capacity of the column and consumes large quantities of mobile phase. Hence, in preparative chromatography, the objective function is productivity, a measure of compromise between the amount of feed that can be loaded on to the column and time. Here, we report results from optimization studies carried out on a closely related binary peptide mixture on an analytical reversed-phase column. The goal is to optimize productivity under various chromatographic modes nonlinear isocratic elution, gradient elution, stepwise elution and displacement chromatography. In each mode, feed mixtures at highest possible concentration (limited by solubility), for increasing feed volumes was used. Productivity was monitored for increasing feed volumes, and loading was stopped as it went through a maximum. However, in some cases, solubility limitations from one of the feed components prevented further increase in loading. Even with this constraint, high productivities (5-10 g product/L stationary phase-h) were achieved. Separate experiments were carried out to measure the adsorption isotherms of these peptides over the range permitted by solubility. Separations under nonlinear chromatographic conditions were applied to isolate commercially significant two microcystins (microcystin LR and microcystin LA) from a cyanobacterial process waste. Milligram-level loading of microcystins was obtained on a solid-phase extraction cartridge packed with 0.5 g of C1 stationary phase. The separations were first carried out on an analytical column and then scaled-up to a preparative column. We also report simple and economical process to purify phycocyanins and allophycocyanins from a cyanobactenal process waste stream for two kinds of applications food colorant and biomedical marker. A detailed design for the large-scale production of biliproteins for both applications is also presented. Economic evaluation of the process resulted in comparable costs with the current market price for food-grade product and substantially lower cost for the biomedical grade product.

Book Description
This interdisciplinary approach combines the chemistry and engineering involved to describe the conception and improvement of chromatographic processes. The book covers recent developments in preparative chromatographic processes for the separation of "smaller" molecules using standard laboratory equipment as well as the detailed conception of industrial chemical plants. Following an introductory section on the history of chromatography, the current state of research and the design of chromatographic processes, the book goes on to define the general terminology. There then follow sections on solid materials and packed columns process concepts. Final chapters on modeling and determination of model parameters, the design and optimization of preparative chromatographic processes and chromatographic reactors allow for the optimum selection of chromatographic systems. Essential for chemists and engineers working in the chemicals and pharmaceutical industries as well as for food technologies, due to the interdisciplinary nature of these processes.

Book Description
This volume provides a straightforward approach to isolation and purification problems with a thorough presentation of preparative LC strategy including the interrelationship between the input and output of the instrumentation, while keeping to an application focus.The book stresses the practical aspects of preparative scale separations from TLC isolations through various laboratory scale column separations to very large scale production. It also gives a thorough description of the performance parameters (e.g. throughput, separation quality, etc.) as a function of operational parameters (e.g. particle size, column size, solvent usage, etc.). Experts in the field have contributed a well balanced presentation of separation development strategies from preparative TLC to commercial preparative process with practical examples in a wide variety of application areas such as drugs, proteins, nucleotides, industrial extracts, organic chemicals, enantiomers, polymers, etc.

Book Description
Completely revised and substantially extended to reflect the developments in this fast-changing field. It retains the interdisciplinary approach that elegantly combines the chemistry and engineering involved to describe the conception and improvement of chromatographic processes. It also covers recent advances in preparative chromatographic processes for the separation of "smaller" molecules using standard laboratory equipment as well as the detailed conception of industrial chemical plants. The increase in biopharmaceutical substances is reflected by new and revised chapters on different modifications of continuous chromatography as well as ion-exchange chromatography and other separation principles widely used in biochromatography. Following an introductory section on the history of chromatography, the current state of research and the design of chromatographic processes, the book goes on to define the general terminology. There then follow sections on stationary phases, selection of chromatographic systems and process concepts. A completely new chapter deals with engineering and operation of chromatographic equipment. Final chapters on modeling and determination of model parameters as well as model based design, optimization and control of preparative chromatographic processes allow for optimal selection of chromatographic processes. Essential for chemists and chemical engineers in the chemical, pharmaceutical, and food industries.
