Column: LC Troubleshooting
Kinetic plots can help us understand how different combinations of parameters will perform in relation the time needed to acquire a particular column efficiency—and thus resolution.
Column: Sample Prep Perspectives
QuEChERS has been updated to suit modern instrumentation. Now also “efficient and robust,” QuEChERSER is a “mega-method” that covers a wider polarity range.
Column: GC Connections
We are all familiar with Golay’s equation relating to height equivalent to a theoretical plate (HETP) in GC. But do we understand it correctly?
Column: Focus on Biopharmaceutical Analysis
We review different approaches and coupling strategies for analyzing monoclonal antibody aggregates with 2D-LC.
Given the excitement surrounding the “green rush,” it is worth stepping back to examine the trends and nuances of the cannabis testing environment.
Compact instrumentation offers important advantages for many workflows, as illustrated by these examples.
Errors arising from the DNPH approach commonly used to analyze carbonyl compounds in smoke from heat-not-burn (HNB) tobacco can be avoided by using the approach described in this study.
