Efficient and Symmetric Temperature Control in Capillary Electrophoresis II: Thermal Performance When Cooling Capillaries Are Tied Around Analytical Capillaries

open access: yesJournal of Separation Science, Volume 48, Issue 8, August 2025.
ABSTRACT Current commercially available capillary electrophoresis instruments lack centrosymmetric and efficient temperature control along the whole extend of the capillary. Here we studied the characteristics and thermal performance of a cooling system that consists of cooling capillaries (fused silica microtubes) which are tied around the complete ...

Separation of Xylidine Isomers by Micellar Electrokinetic Chromatography [PDF]

open access: yesJournal of Chromatographic Science, 2001
Xylidines are important precursors for the production of dyes, drugs, and various other products. Because of the high carcinogenic nature of some xylidine isomers it becomes very essential and relevant to develop suitable analytical procedures to separate isomers as well as enhance detection at very low concentrations.

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

open access: yesELECTROPHORESIS, 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.

Gradient micellar electrokinetic chromatography.

open access: yesSEIBUTSU 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.

Analysis of carbohydrates and glycoconjugates by matrix‐assisted laser desorption/ionization mass spectrometry: An update for 2021–2022

open access: yesMass Spectrometry Reviews, Volume 44, Issue 3, Page 213-453, May/June 2025.
Abstract The use of matrix‐assisted laser desorption/ionization (MALDI) mass spectrometry for the analysis of carbohydrates and glycoconjugates is a well‐established technique and this review is the 12th update of the original article published in 1999 and brings coverage of the literature to the end of 2022.
