GC-MS – News and Features

Many people are now open to trying plant-based alternatives, as long as they closely resemble the taste, odor, appearance and texture of real beef. Now, researchers report that the aromas of a couple of plant-based burgers come close to the real deal when they are cooking.

Scan the menu top restaurants and you may encounter premium ingredients that promise an exceptional dining experience. But what do we really know about such products, other than what the labels would have us believe? Sometimes, surprisingly little.

In this article, David Elder discusses the identification of N-nitrosamine impurities in valsartan drug substances products in mid-2018 and highlights the regulatory response, sources of contamination and analytical methods used for identifying nitrosamines.

In this article, we take a look at the fundamentals of mass spectrometry, how it works, variations that can be used at each stage of the process and how they can be combined to suit different sample types or analytical questions.

In this article, we bring together resources from the across the site on gas chromatography, how it works, its pairing with downstream techniques and what its applications are.

Researchers have discovered a method that can improve the world's crops. The new approach to cereal plant breeding takes into account the internal "calculator" of plant seeds that makes them continuously reorganize themselves (global coherence).

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.

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 (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.

In this article, we take a look at what gas chromatography is, how it works and how to interpret output data. Its combination with mass spectrometry and the use of multiple dimensions are considered.
