In this study, an empirical assessment of summation integration (using the lowest baseline point in user-defined tR windows) was conducted involving 490 low-pressure GC–MS/MS analyses of 70 pesticides in 10 common fruits and vegetables over the course of 10 days.

Separating proteins and antibodies is a unique analytical challenge because of the complexity of the analytes. Both sample heterogeneity, because of a number of chemical modifications to the analyte, and nonspecific binding to the silica surface often result in chromatographic peak broadening and tailing. This instalment of “Column Watch” focuses on several different chromatographic strategies that analytical scientists can use to resolve and quantitate various biomacromolecules, including monoclobal antibodies (mAbs) and antibody–drug conjugates (ADCs). Selected aspects of size-exclusion, hydrophobic interaction, ion-exchange, hydrophilic interaction, and reversed-phase chromatography are discussed.

This instalment on ultrahigh-pressure liquid chromatography (UHPLC) reviews the potential problems that may be encountered using UHPLC systems and methods, and proposes strategies for their mitigation.
