Influence of metallic, ceramic, and plastic MALDI surface materials on the ionization efficiency and quality of mass spectrometric data

Hieke A., Stanford University, School of Medicine, US

Imperfections of the MALDI ionization process of proteins and peptides impose considerable limitations on the utility of mass spectrometry in basic life sciences and ultimately on the application in biomarker discovery and medical diagnostics. Improved [...]

Analysis of Sample Transport in Capillary Electrophoresis Microchip Using Full-Scale Numerical Analysis

Krishnamoorthy S., Feng J.J., Makhijani V.B., CFD Research Corporation, US

An implicit finite-volume numerical scheme has been developed to solve the three-dimensional transport equations along with fully-coupled ionization equilibria in acid/base systems. The scheme solves conservation equations for mass and momentum while satisfying the electroneutrality [...]
