Preferred Label : mass distribution ratio;
Detailed label : mass distribution ratio in micellar electrokinetic chromatography, kMEKC;
IUPAC definition : Defined as: \[k_{{MEKC}} \frac{n_{{mc}}}{n_{{aq}}} K\cdot \frac{V_{{mc}}}{V_{{aq}}}\]
where n mc and naq are the chemical amounts of the analyte in the micellar and aqueous
phases, respectively, K is the distribution constant and V mc and Vaq are the corresponding
volumes of the phases.;
Scope note : kmekcshould not be confused with the retention factor (in column chromatography)
k. however, kmekc is analogous to the mass distribution ratio (in chromatography).; in the case of an electrically neutral analyte, kmekc can be calculated directly
from the migration times: kmekc tm teo teo
1 tm tmc;
Origin ID : MT06928;
