Effects of Sample Diluent on Analyte Recovery in Reversed-Phase and HILIC Separations
Carefully diluting a sample with weak solvent can mitigate the impact of sample solvent on peak shape in both reversed-phase and HILIC separations, but we need to understand how the choice of sample diluent can affect analyte recovery.
Essential GC Accessories
Although manufacturers ship gas chromatographs with a collection of consumable parts and accessories, a number of other essential items should be on hand in every GC laboratory. What items are needed and how can they be used most effectively?
An Introduction to Glycan Analysis
Glycosylation is the most common monoclonal antibody (mAb) posttranslational modification. What is essential to know about it?
Data Integrity Focus, Part VIII: What is Good Documentation Practice (GDocP)?
