The known mode of chromatographic quantification by the method external standard is based on comparison average absolute peak areas analyte(s) for target samples ( S x ) and additionally prepared standards stand ). This characterized valuable “sensitivity” results in relation to repeatability measured areas. In modified standard, equal amounts additional are added samples; ratios / add.stand used subsequent data processing. not described contemporary scientific teaching literature gas...
Microemulsion electrokinetic chromatography (MEEKC) is a promising method for separating ionic and neutral analytes in the complex matrix, where microemulsion used as background electrolyte. Current work identified possibility of using hydrophilic liquids (ILs) based on imidazole (C 12 MImCl, C 16 MImCl) modifiers surfactants, well hydrophobic ILs 6 MImBF 4 ) an “oil” separation steroid hormones by MEEKC. The factors such concentration, nature pH electrolyte, ratio components microemulsion,...
