2. Automating the Control of Process-Scale Purification Columns Using On-Line Liquid Chromatography.

Author

Cooley, Rick E.

Subjects
CHROMATOGRAPHIC analysis, HIGH performance liquid chromatography, CHEMICAL purification, ANALYTICAL chemistry, CHEMICAL process industries, BIOPHARMACEUTICS
Abstract

The article focuses on the significance of on-line high-performance liquid chromatography (HPLC) in measuring product purity in the column eluent stream in near-real time. On-line HPLC monitors the eluent from process-scale columns. It allows process decision based on critical quality rather than on a surrogate measurement. Its data enable the automation and control of a purification column operation. It is also used as a process analytical technology ensuring the accommodation of variability.

3. Amide Hydrogen-Deuterium Exchange: A Fast Tool for Screening Protein Stabilities in Chromatography.

Author

Fogle, Jace L. and Fernandez, Erik J.

Subjects
*CHROMATOGRAPHIC analysis, *ANALYTICAL chemistry, *PROTEINS, *HYDROGEN, *DEUTERIUM, *CHEMICAL purification
Abstract

The article discusses the methodology for using amide hydrogen-deuterium exchange with chromatographic materials as a means to identify buffer and resin conditions that are destabilizing to specific proteins. It is found that amide hydrogen-deuterium exchange is a powerful tool for fast resin screening during purification process development.

4. Chiral Analysis and Purification Using Kromasil CelluCoat.

Author

Kofoed-Hansen, Britt

Subjects
*CHROMATOGRAPHIC analysis, *SILICON compounds, *ORGANIC compounds, *ANALYTICAL chemistry, *CHEMICAL purification
Abstract

The article focuses on the use of Kromasil CelluCoat in the analysis and purification of chiral compounds. Kromasil CelluCoat refers to a silica based chiral stationary phases (CSP) coated with tris-carbamoyl cellulose as the chiral selector. The analysis involves a factor of selectivity that leads to enantiomer separation, which leads to the speed of separation.

5. New Polymeric Reversed-Phase Columns for Peptide Separations.

Author

Maikner, J., Fisher, J., Gehrls, A., Sherkness, A., Kinzey, M., and Vanderhof, M.

Subjects
*CHEMICAL purification, *PEPTIDES, *OLIGONUCLEOTIDES, *CHROMATOGRAPHIC analysis, *VACCINES, *ANALYTICAL chemistry
Abstract

The article present information about introduction of new polymeric reversed-phase columns, Amberchrom™ Profile™. These columns have been developed for the purification of peptides and oligonucleotides by reversed-phase chromatography. The columns have been able to achieve the purification target yield of eighty percent at more than ninety five percent purity in the purification of influenza peptide, that is used in the area of vaccine development..

8. Flash Purification of δ-Tocopherol and Subsequent HPLC Analysis for Sample Purity.

Author

Lloyd, L., Ball, S., and Mapp, K.

Subjects
*CHEMICAL purification, *HIGH performance liquid chromatography, *CHROMATOGRAPHIC analysis, *ANALYTICAL chemistry, *VITAMIN E
Abstract

The article discusses a study on the flash purification of δ-tocopherol and high performance liquid chromatography (HPLC) analysis for sample purity. It defines HPLC as a method using small particle media, while flash purification as a technique using larger particle media. It discovers that chromatographic separations can be transferred between HPLC and flash purification and both methods save time and money.
