Journal ArticleDOI
Monolithic silica columns for high-efficiency chromatographic separations
Nobuo Tanaka,Hiroshi Kobayashi,Norio Ishizuka,Hiroyoshi Minakuchi,Kazuki Nakanishi,Ken Hosoya,Tohru Ikegami +6 more
TL;DR: Monolithic silica columns prepared from tetraalkoxysilane by a sol-gel method showed high efficiency and high permeability on the basis of the small-sized silica skeletons, large-sized through-pores, and resultingThrough-pore size/skeleton size ratios much larger than those found in a particle-packed column.
Journal ArticleDOI
Separation efficiencies in hydrophilic interaction chromatography.
TL;DR: This review discusses the column efficiency of HILIC materials in relation to solute and stationary phase structures, as well as comparisons between particle-packed and monolithic columns.
Journal ArticleDOI
Monolithic silica columns for HPLC, micro-HPLC, and CEC
Nobuo Tanaka,Hisashi Nagayama,Hiroshi Kobayashi,Tohru Ikegami,Ken Hosoya,Norio Ishizuka,Hiroyoshi Minakuchi,Kazuki Nakanishi,Karin Cabrera,Dieter Lubda +9 more
TL;DR: In this article, two types of monolithic silica columns derivatized to form an ODS phase, one prepared in a fused silica capillary (SR-FS) and the other made in a mold and clad with an engineering plastic (poly-ether-etherketone) was evaluated.
Journal ArticleDOI
Monolithic silica columns with various skeleton sizes and through-pore sizes for capillary liquid chromatography.
Masanori Motokawa,Hiroshi Kobayashi,Norio Ishizuka,Hiroyoshi Minakuchi,Kazuki Nakanishi,Hiroshi Jinnai,Ken Hosoya,Tohru Ikegami,Nobuo Tanaka +8 more
TL;DR: Although a column with smaller domain size generally resulted in higher separation impedance and the lower total performance, the monolithic silica columns showed performance beyond the limit of conventional particle-packed columns under pressure-driven conditions.
Journal ArticleDOI
Monolithic silica columns for high-efficiency separations by high-performance liquid chromatography.
Norio Ishizuka,Hiroshi Kobayashi,Hiroyoshi Minakuchi,Kazuki Nakanishi,Kazuyuki Hirao,Ken Hosoya,Tohru Ikegami,Nobuo Tanaka +7 more
TL;DR: The monolithic silica columns showed performance beyond the limit of conventional particle-packed columns in HPLC under favorable conditions, and for solutes with large retention factors due to the slow mobile-phase mass transfer in the large through-pores.
