A group of researchers have characterized carotenoid and chlorophyll in different sweet bell peppers using offline multidimensional supercritical fluid chromatography (SFC) combined with reversed-phase liquid chromatography (LC) for the first time.

Phenomenex has announced that it will be acquired by Danaher Corporation, a Fortune 150 science and technology company. Phenomenex will continue to operate as a standalone company, and will retain the Phenomenex brand, its personnel, and site locations.

Discovering and identifying molecular biomarkers in large liquid chromatography–mass spectrometry (LC–MS) data sets requires automation without loss of accuracy. Benjamin Van Mooy from the Wood Hole Oceanographic Institution reveals a lipidomics strategy using LOBSTAHS to identify lipid, oxidized lipid, and oxylipin biomarkers in high mass accuracy high performance (HP) LC–MS data.

Incognito feels a change is needed.

Researchers have developed a method to quantify concentrations of the pollutant tributyltin (TBT) in whole water bodies using species-specific isotope dilution (SSID) and gas chromatography with inductively coupled plasma mass spectrometry (GC–ICP-MS).

This article highlights the analytical advantages of analyzing raw milk for aflatoxins, focusing on M1, using high performance liquid chromatography (HPLC) with fluorescence detection - without derivatization. Leveraging M1’s native fluorescence, this is particularly welcome since this approach affords the requisite analytical sensitivity with minimal method complexity.

The migration of chemicals through polymeric materials is difficult or impossible to model theoretically, placing an emphasis on experimental assessment to provide reliable empirical data. This article describes an investigation into the permeation of volatile chemicals through thin polymer membranes based on dynamic headspace, and how the information generated may be of value industrially - specifically in the fields of food packaging and personal protective equipment.
