Eli Grushka, a professor emeritus of analytical chemistry at the Hebrew University of Jerusalem's Chemistry Institute, passed away on March 22 after a brief illness. Grushka was the president of the Israel Society for Analytical Chemistry for many years and served on the organizing committee of the annual Isranalytica meeting, the largest analytical chemistry meeting in Israel.

Researchers from South Korea have investigated methods of reducing polycyclic aromatic hydrocarbons within cooked meat using gas chromatography–mass spectrometry.

E-Separation Solutions

A team of researchers has developed a high-throughput analysis method for 192 diverse pesticides and 51 environmental contaminants (13 polychlorianted biphenyl [PCB] congeners, 14 polycyclic aromatic hydrocarbons [PAHs], seven polybrominated diphenyl ethers [PBDE] congeners, and 17 novel flame retardants) in cattle, swine, and poultry meats. The team used a combination of low-pressure gas chromatography coupled to tandem mass spectrometry (LP)GC–MS–MS and ultrahigh-pressure liquid chromatography coupled to tandem MS in the analysis.

A team of researchers from China and the USA has developed a LC–MS–MS method for quantifying methylergonovine, a semi-synthetic ergot alkaloid used for the treatment and prevention of postpartum haemorrhage in human plasma.

Thermal desorption sampling often provides a means for bringing otherwise intractable samples to a gas chromatography (GC) column for separation and detection. In this instalment, John Hinshaw describes the principles of thermal desorption sampling in relationship to other analysis techniques for volatile solutes.

The literature on reversed-phase liquid chromatography of proteins is reasonably well developed, but not taught in the college classroom to a significant degree. So I would like to focus on a stoichiometric displacement model for reversed-phase LC of proteins that I found to be particularly insightful from a practical standpoint.
