Application of Silica Monoliths for Bioanalysis
In this article, the application of silica monoliths with bimodal pore structure (macro and mesopores) is described for the chromatographic analysis of biomolecules including peptides, proteins, and antibodies.
Improved LC–MS Performance — A Three-Step Method for Minimizing Background Signals and Increasing Ionization Efficiency
One problem frequently encountered in LC–MS is the appearance of mass peaks, which appear totally unrelated to the samples run - "ghost" mass peaks. It is impossible to differentiate whether these signals come from an unknown component in the sample co-eluting with a known peak, or from an impurity in the mobile phase or from some residual contamination "bleeding" from the column.
