Convergent coordinatesBy plotting of the affinity of component to adsorbent ( β a ) vs . the logarithm of the solvent activity in the mobile phase in a reversed phase HPLC system, it is shown that when the concentration of organic solvent in the mobile phase increases, β a of a series ...

However, this drawback is compensated by the phase ratio VS/VM (stationary phase volume over mobile phase volume) which can be higher than 1 in CCC and is lower than 0.05 in LC. The resolution factor, Rs, can be higher than 1.5 in CCC for solutes with partition coefficients around 1. ...
Finally, in addition to all these behavioral differences found in eye movement studies in natural environments and laboratory settings, it is of the utmost importance to evaluate any technical differences between mobile and laboratory-based eye-trackers—for example, in terms of accuracy and the typic...
mobile phasepH, and the nature of both theeluention and the analyte ion, dynamic capacity can only be measured empirically and has no fundamental relationship to the static capacity. For example, if the eluent consists of a strongly retained ion and the sample consists of a weakly retained ...
Actual operational data from the Chinese HRSs show that the temperature inside the storage tank drops by 1–5 °C during the filling of FCEVs, which is mainly due to the reduction of hydrogen inside the container during the refueling process. However, during the idle phase, i.e., the ...
Experiments were performed at constant mobile phase composition in the temperature range 5-40°C to study the effect of temperature. Thermodynamic parameters were calculated on the basis of the plots of ln α vs. 1/T curves. The enthalpically or entropically driven enantioseparations were found ...

of a single cell to the system and the neighboring cells to avoid cascading (propagation) of the thermal runaway. Examples are the use of thermal insulation to limit heat transfer from a cell under TR to neighboring cells or phase change materials which absorb the heat of a single cell TR...
By employing a mobile phase consisting of acetonitrile/methanol/water/acetic acid (96:2:2:0.1, v/v/v/v), nearly complete baseline separation (with α=1.08) of allantoin enantiomers was achieved in less than 15 min with both CSPs. Due to the “pseudo-enantiomeric” nature of the two ...
