Determination of association constants of inorganic ions with C12- and C14-alkyldimethylammoniopropane sulfonate zwitterionic surfactants using capillary electrochromatography

Effect of perfluorinated surfactant as additive of background electrolyte for capillary electrophoresis of inorganic cations

“…In contrast, the differences in these affinities for monovalent cations were too small among the surfactants. The order of K ass values of analyte cations for Brij35 and C12N3S agreed with the results obtained by Yokoyama et al [37], and this order for PFOSA was corresponded to the small differences in K ass values of monovalent cations.…”

Crystal Structure of Zwitterionic Trimethylammoniopropane Sulfonate

“…Also, the zwitterion, Z1-Methyl, is useful as an additive to control an electroosmotic flow (EOF) without any change of the electric currents for capillary electrophoresis (CE). 2 The crystal structure of Z1-Methyl would give information on the effect of functional groups in Z1-Methyl on EOF control in CE.…”

“…Accordingly, Z1-Methyl could control the EOF with increasing its concentration in an electrophoretic buffer. 2 + 2U12(aa*bb*)cos + 2U13(aa*cc*)cos + 2U23(bb*cc*)cos ). π β α γ Table 3 Bond lengths (Å) and angles (˚) Fig.…”

Retention Behavior of Inorganic Anions in Hydrophilic Interaction Chromatography

“…6 Besides, some stationary phases, where there is no positive/ negative charge, could achieve the separation of ions by dynamically coating ionic reagents, such as ion-pairs reagents or surfactants. [7][8][9][10] It was also found that some inorganic anions could be separated on the C30 stationary phase by the hydrophobic interaction. 11 The separation of inorganic anions in the partition mode was observed by the C30 stationary phase coated by poly(ethylene glycol) (PEG).…”
