retention model
Its coordinates depend on the series and the solvent used, and can be rationalized on the basis of the retention model of interaction indices.
      
A simple retention model based on interaction indices allows easy prediction of retention in reversed-phase liquid chromatography.
      
The "diachoric" model stems from the assumption that the mobile phase is microscopically heterogeneous and the "displacement" model is identical to the retention model most widely used in chromatography with polar sorbents and less polar solvents.
      
The adequacy of the proposed PAH retention model was verified by comparing the calculated retention values with the experimental data.
      
In our retention model major importance is attributed to the self- and mixed association of the mobile phase molecules, and the quantification of this effect represents a crucial part of our approach.
      
For some classical gel filtration chromatographic gels, the fractal retention model does not seem to apply.
      
In our previous publications we have established a new physico-chemically grounded retention model valid for the adsorption and partition mechanism of retention using multicomponent mobile phases.
      
The retention model is based on studies of the influence of concentration of divalent counter ions, dihydrogen phosphate and sodium, as well as pH, on the retention of mono- and divalent naphthalenesulphonates.
      
This is done with help of the new retention model presented earlier as the relationship for the retardation coefficient (RF) of solute.
      
The retention in GLC can be predicted with help of our thermodynamic retention model.
      
We apply our new retention model introduced elsewhere to the studies of intermolecular interactions between the solute and the remaining components of a normal-phase HPLC system using a binary mobile phase consisting of an alcohol and a hydrocarbon.
      
In this paper the new retention model primarily established for RP-HPLC systems employing methanol-water mobile phases has been adapted to the description of solute retention in analogous systems using methanol-phosphate buffer mixtures.
      
Estimation of the degree of self-association of water using a novel retention model
      
This was only possible with the use of a new solute retention model for the chromatographic systems by considering intermolecular interactions between the constituents of binary mobile phases.
      
A retention model is presented and used qualitatively in the study of the effect of DBT concentration, organic solvent, addition of a competing amine and packing material on retention and stereoselectivity.
      
The competitive complexation between solute and hydroxide to the metal ions is described as a ligand exchange reaction and a retention model is proposed.
      
The method is based on a retention model which describes the dependence of the logarithm of the capacity factor on mobile phase composition and the carbon number of specific homologous series.
      
Retention model by formal analogy with conductance of elec
      
Retention model by formal analogy with conductance of elec
      
A retention model was developed by correlating the logarithm of the retention factor with the hydrophilic-lipophilic balance of the analyte.
