Microplastic Analysis and the Future Detection Landscape

The full impact that microplastics have on health and the environment is still not well understood, however, mounting evidence regarding their negative effects has made microplastics a topic of interest for scientists, governments and regulatory bodies. We spoke to Kathleen A. Young about microplastics detection techniques and technologies, the importance of standards and how regulations may come to fruition in the years to come.

The Evolving Problem of Microplastics in a PPE Era

Microplastics are now ubiquitous in our lives and environment. To compound the problem, the advent of COVID-19 has seen uptake of single-use plastics in the form of personal protective equipment (PPE) skyrocket. We spoke to Kathleen A. Young about how the microplastics issue has evolved in light of COVID-19, particularly around PPE waste and what gains are being made in the areas of testing and analysis standards.

Liquid Chromatography – Including HPLC, UHPLC and LCxLC

Liquid chromatography (LC) is a technique used to separate and analyze mixtures of chemical components in solution, to determine if a specific component is present and if so, how much of it is there. In this article we explore how LC works, how the technique has evolved, LC data interpretation and strengths and limitations.

Picking Out Hoppy Beer's Fruity Thiols

Brewers have been looking for an accurate way to track thiols in beer, that give it the pleasant fruity aroma. But current methods typically are not sensitive enough or require the use of potentially harmful substances. Now, researchers present an automated, solvent-less process to assess thiols at very low concentrations.
