This study explores orthogonal pressurised planar electrochromatography for separating complex mixtures. It presents methods to determine optimal sample loads and compares its efficiency with other techniques for enhanced separation productivity.
Area of Science:
- Analytical Chemistry
- Separation Science
- Chromatography
Background:

Crystal Field Theory - Tetrahedral and Square Planar Complexes
Crystal field theory (CFT) is applicable to molecules in geometries other than octahedral. In octahedral complexes, the lobes of the dx2−y2 and dz2 orbitals point directly at the ligands. For tetrahedral complexes, the d orbitals remain in place, but with only four ligands located between the axes. None of the orbitals points directly at the tetrahedral ligands. However, the dx2−y2 and dz2 orbitals (along the Cartesian axes) overlap with the ligands less than the dxy,...
