Liquid Chromatography (LC/HPLC)

A harmonization of all conventional hold-up volume methods was successfully applied to RPLC, HILIC, AEX, and RP-AEX mixed-mode chromatography, regardless of the mobile phase.

Developing a short list of the likely causes of these results can help streamline our troubleshooting experience when sensitivity-related problems occur.

The Column spoke to Brett Paull from the University of Tasmania in Hobart, Australia, about the development of truly portable LC systems for use in the pharmaceutical industry and in environmental analysis. Why are they necessary, and where can improvements still be made?

I recently read a nice article from The Robot Report (1) that contrasted the performance of robots in industry against those of humans. The takeaways from the report are as follows.

What’s the fastest way to acquire a new chromatographic skill? The answer lies with those who are just beginning to learn.

Knowing the tips and tricks of producing quality LC–MS data for peptide analysis can help streamline troubleshooting when problems occur.

There are various physical and chemical causes of low detection sensitivity. Here, we address some of these causes, and how to troubleshoot them.

The application of porous layer open tubular (PLOT) columns can be expanded beyond light compounds to separations of analytes with heavier boiling points.

This case study of the career path of a separation scientist illustrates the diversified roles of an analytical chemist in nonclinical drug development.

The return of the in-person HPLC Conference was welcomed by the separation science community. There were a lot of developments to share.
