Download or read book Chemically Modified Silica Surfaces in Chromatography written by Martin J. J. Hetem and published by . This book was released on 1993 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first part discusses several investigations into the optimization of deactivation and coating both of fused silica capillary columns for GC and of a nonporous silica model substrate. The second part describes surface characterization studies of a number of selected chemically modified silica gels: when modified silica gels are used in RPHPLC practice, unfavorable changes in chromatographic performance occur. The observed changes in surface structure are discussed in detail.
