The American Chemical Society’s National Historic Chemical Landmarks program highlights sites and people that are important to the field of chemistry. How are analytical chemistry and separation science recognized within this program?

In this episode, podcast co-hosts Dr. Dwight Stoll and Dr. James Grinias discuss highlights and observations from HPLC 2024, which was held in Denver, Colorado in July.

In this installment, we apply the concepts developed in last month’s installment by demonstrating how they can be used to help troubleshoot problems in LC involving pressure and flow.

The analogy that electrons flowing in wires is like water flowing through a tube can be remarkably effective. In this installment, the basics of that analogy are discussed.

For this year’s career issue, LCGC North America teamed up with the American Chemical Society Subdivision on Chromatography and Separations Chemistry to ask the analytical chemistry community what skills new employees in the field need to succeed. In this report, we analyze the survey results and explore how they can inform the future of analytical chemistry curriculum development.

A recent trend in the design of LC instrumentation is the move towards miniaturized and portable systems.

The fundamental mechanisms of band broadening are usually introduced to students through the van Deemter equation. Dimensional analysis of this equation can give physical meaning to the equation coefficients and enhance our understanding relative to qualitative descriptions. This approach can also guide improvements to future liquid chromatography (LC) column designs.

Compact instrumentation offers important advantages for many workflows, as illustrated by these examples.

At the 43rd International Symposium on Capillary Chromatography (ISCC 2019) in Fort Worth, Texas, a panel addressed the current challenges and potential future directions in capillary liquid chromatography. How can their vision be achieved?
