Design and characterization of novel stationary phases based on retention behavior studies with various aromatic compounds

Abstract: Design and characterization of novel stationary phases based on retention behavior studies with various aromatic compounds Characterization of stationary phases by retention behavior studies with aromatic compounds is reviewed, focusing mainly on the authors' approach. Various aromatic compounds, such as polycyclic aromatic hydrocarbons (PAHs) and fullerenes, of different molecular shape and size were employed as the sample probes. For the systematic analysis of retention behavior, some spectroscopic technique… Show more

“…18,19 On the contrary, when the column temperature was elevated with MeOH-based mobile phases, all the retention factors were gradually decreased, as normally found in typical RPLC separation conditions. [20][21][22][23][24] Similar trends were also observed for all other alkyl-bonded stationary phases employed in this work.…”

“…3,4 The use of a miniaturized column also permits an effective employment of temperature-programmed elution, due to a smaller heat capacity of the column. Although the effect of the temperature in typical LC using a chemically modified silica-based material, such as octadecylsilica (ODS), has been regarded as a minor parameter affecting the separation when compared with that in gas chromatography (GC) separation, the temperature effect on LC separation has been studied; [4][5][6] also the advantages in high-temperature LC have been reviewed by Greibrokk et al 7,8 Teutenberg et al determined the vapor pressures, viscosities and static permittivities of simple solvents and binary solvent mixtures used in reversed-phase liquid chromatography in given temperature ranges, and extensively discussed the influence of temperature on reversed-phase LC along with the strategy for temperature programming. [9][10][11][12][13][14] By introducing fine fibrous materials as the extraction medium, several novel microscale sample preparation techniques were developed based on excellent resistance to typical organic solvents.…”

“…Ohta and co-workers studied the retention behavior of fullerenes from -70 to 80 °C and confirmed a unique relationship between temperature and retention on monomeric ODS phases (26)(27)(28)(29)31). They found the existence of a critical temperature at which the retention of each fullerene molecule was maximized ( Figure 2); however, this maximum retention temperature differed, depending on the surface coverage of the ODS phase.…”
