The potential of food packaging components to migrate into food is an important health concern. Perfecto Paseiro Losada and his group at the University of Santiago de Compostela, in Spain, have been investigating the migration kinetics and actual migration of such compounds into a variety of types of food. They also have been carrying out studies to estimate dietary exposure. Paseiro recently spoke to LCGC about this work.

Fundamentals aspects of using HPLC techniques for protein analysis are described as they relate to the analysis of post-translational modifications (PTMs) and glycoprofiles.
The 2020 winners of the LCGC Lifetime Achievement in Chromatography Award and the Emerging Leader Award have been selected.
In HPLC Diagnostics Skills Part I we looked at baseline issues, and we continue here with HPLC peaks and in particular the skills required to identify tailing peaks, the causes of peak tailing, and most importantly, how to fix the issues that give rise to this peak deformation.

The sample solvent can have a big impact on peak shape in both reversed-phase and hydrophilic interaction liquid chromatography (HILIC) separations, especially when large volumes are injected. Diluting the sample with weak solvent can be an effective solution to mitigate this problem, but we have to be careful to not lose analytes of interest to precipitation or phase separation.

Most manufacturers ship gas chromatographs with a small collection of consumable parts and accessories, such as extra ferrules, inlet liners, or septa, and a few instrument-specific tools. In earlier times, some convenience items might have been included as well, like a bubble flow meter or a small set of tools, but now it’s rare to find such things in the shipping boxes. This edition of “GC Connections” lists a number of essential items that should be on hand in every gas chromatography (GC) laboratory, their function, and how to use them effectively.

The occurrence of additives, such as plasticizers in plastic food packaging, has been documented, but information on their potential migration into foods is limited. In this pilot study, 2D GC–MS was used to identify chemicals extracted from a common stretch plastic film with a series of organic solvents.

For decades the prevailing perception was that satisfactory re-equilibration of reversed-phase columns following gradient elution took a long time. In the early 2000s we showed that this perception was not well founded, and demonstrated that adequate re‑equilibration could be achieved in seconds. Recently, we have shown the same for HILIC columns. All of this work so far has been with small molecules. In this article, we present an overview of this work, and summarize the practical utility of it all.
