Gradient micellar electrokinetic chromatography.

SEIBUTSU BUTSURI KAGAKU, 2008
A Surfactant gradient method was developed for miceller electrokinetic chromatography (MEKC). In the present method, electroosmotic flow was suppressed almost completely and thus, micelles in a running solution of the inlet vial were introduced in turn into the capillary during operations.

Peak Integration of Electropherograms in GMP and Research Labs: Navigating Increased Scrutiny Amid Data Integrity Audits and Inspections

ELECTROPHORESIS, Volume 46, Issue 11-12, Page 653-668, June 2025.
ABSTRACT Capillary electrophoresis (CE) often offers superior separation relative to chromatography for macromolecules like monoclonal antibodies (mAbs), a major pharmaceutical class. However, electropherogram baselines pose challenges that traditional chromatography algorithms cannot address, requiring complex integration processes.
