When esterification occurs in your LC mobile phase, knowing how baseline quality, retention, and selectivity are affected will help you mitigate the effects.

At HPLC 2022, we heard about new research and developments, in areas such as column technologies, portable instrumentation, and machine learning, among others.

Can you pass this test of chromatographic sample preparation concepts?

We pass on valuable lessons shared by the six GC speakers at ChromTalks 2022.

This method greatly facilitates the analysis of a large number of pesticides.

We analytical chemists have a lot to gain by applying machine learning to our field—such as by using it to efficiently reach optimal conditions for challenging separations.

In this study, the experimental nontargeted screening approach and corresponding data analysis workflows—simultaneously using molecular ion information and structural information—are presented for the molecular identification and authenticity verification process from a brand perfume using GC–ecTOF-MS.

Online 2D-LC is a powerful—and accessible—tool for analyzing pharmaceutical and biopharmaceutical samples, in both R&D and QC. It’s now easier than ever to develop 2D-LC methods, and they can be run in a fully automated manner.
