The global economy is currently going through something it has not experienced in nearly a decade. The major geographic segments are performing well with overall production increasing. This is typically a strong indicator that the demand for chromatography products in the chemical and petrochemicals industry will also perform well.

Gas chromatography makes use of a wide variety of detection methods, which really shine when deployed properly. Here’s guidance for how to choose the right one for your analysis.

Parameters such as pore size, column dimensions, temperature, flow rate, and mobile phase are important to consider when developing SEC methods.

A look at recent advances in SPME, such as increasing the sorbent surface area available for extraction, accommodating direct analysis by mass spectrometry, and sorbent overcoating to resist fouling by sugars and lipids

Certain details related to mobile-phase preparation that can be assumed in reversed-phase LC separations can be much more consequential in HILIC.

Because not all laboratories have UHPLC systems, reverse scaling of methods from UHPLC to HPLC is often needed, particularly in the pharmaceutical industry. The use of superficially porous particles can facilitate this process.

This article, the first in a series on chromatography fundamentals, discusses the cornerstone of all chromatographic techniques-the distribution or coefficient-and its influence on liquid chromatographic separations.

A summary of the findings presented at the HPLC 2017 Jeju conference, reviewing how they fit into overall liquid-phase separation trends and the outlook for the future of these technologies
