Pressure influence of capacity factorThe pressure applied in liquid chromatography (LC) can influence the capacity factor of analytes. Using commercial equipment, column (33脳4.6 mm) and 1.5 渭m non-porous, tetradecyl (C 14 ) coated silica particles, a moderate but significant change in the ...
The role of the redox potential as a factor contributing to the NO-generating activity of these two proteins is evaluated. The results show that LtHb undergoes the same reactions as HbA and that the reduced efficacy for these reactions for LtHb relative to HbA is consistent with the much ...
The equations developed here for the peak capacity and peak capacity per unit time in capillary and microchip zone electrophoresis, based on a 3/2-power time dependence of peak width (assuming similar diffusion coefficients), allow one to precisely calculate an unbiased upper limit for what can ...
Nannochloropsisdemonstrated superior effectiveness compared toChlorellaandArthrospirain enhancing the vegetative growth of common bean plants. The most significant improvement in growth traits such as PH, RL, LN, LA, FW, and DW was observed with a concentration of 0.5%Nannochloropsis. Following closely b...
This paper is concerned with the problem of obtaining phosporamidic derivatives by an original synthesis, the compound separation by HPLC, founding molecular descriptors and their correlation for mathematical description of parameters that influence the capacity factor.Maranescu...

Lipophilicity has also been determined using HPLC on a styrene/divinylbenzene polymeric stationary phase in methanol/water and acetonitrile/water media. Correlations between log Poct, and HPLC capacity factor log k' are established. On the basis of our results, the fragmental contribution of the...
In this paper, we are advocating the use of peak capacity as such a measure in the case of a gradient separation, and we will develop the underlying theory. A very good definition of peak capacity has been provided by Giddings in his early work: “The peak capacity is the upper limit ...
However, the main drawbacks such as low specific surface areas, poor structural stability and difficult separation limit its further applications [20]. Preparing the double-layer structure of hybrid MOFs by coating ZIF-67 onto the surface of ZIF-8 may be a feasible way to overcome the above...
