An in-line mixer between the sample injector and column may resolve problems with peak shape caused during sample dilution.

Gaining a solid understanding of how HPLC instrumentation works will help you achieve success in the analytical laboratory. This four-part series is here to guide you, starting with pumps.

What are the roles and responsibilities of quality assurance staff for ensuring data integrity in an organization?

Coupling CE with MS presents some challenges. Here, we discuss the advantages of CE–MS over LC–MS, and the parameters that are important to obtain a stable CE–MS profile.

Improved practices in chemistry selection and sample processing may resolve recovery issues related to target analytes or internal standards.

Unlike reversed-phase liquid chromatography, SFC lacks a universal stationary phase. Thus, it is important to re-evaluate the default column screening library used with SFC. In this study, three uncommon achiral SFC columns were investigated and compared to three popular stationary phases.
