Jefferey Shabanowitz, a principal scientist at the Hunt Laboratory at the University of Virginia (Charlottesville, Virginia), will receive the Al Yergey Mass Spectrometry Scientist Award at the American Society for Mass Spectrometry (ASMS) conference on Monday, June 3, at the Georgia World Congress Center in Atlanta, Georgia.

The 2019 Ron Hites Award, to be presented on Wednesday, June 5, at the Georgia World Congress Center in Atlanta, Georgia, will honor Julia Laskin of Purdue University (West Lafayette, Indiana) and her coauthors for their paper, “Towards High-Resolution Tissue Imaging Using Nanospray Desorption Electrospray Ionization Mass Spectrometry Coupled to Shear Force Microscopy.”

The winners of the 2019 Research awards from the American Society for Mass Spectrometry (ASMS) are James F. Davies of the University of California, Riverside; Nicolas L. Young of Baylor College of Medicine (Houston, Texas); and Eleanor Browne, of the University of Colorado, Boulder.

John R. Yates III, a professor in the Department of Molecular Medicine at The Scripps Research Institute (La Jolla, California), will receive the John B. Fenn Award for a Distinguished Contribution in Mass Spectrometry at the American Society for Mass Spectrometry (ASMS) conference on Monday, June 3, at the Georgia World Congress Center in Atlanta, Georgia.

The 48th International Symposium on High Performance Liquid Phase Separations and Related Techniques (HPLC 2019) will be held 16–20 June 2019 at the Milano-Bicocca University, in Milan, Italy. This is the first time that this symposium will be held in Italy.

Pharmaceutical and personal care products (PPCPs) are routinely detected in a variety of aquatic environments and these compounds encompass a wide range of chemical and physical properties that contribute to their combined analytical screening challenges. Further examination of their accumulation throughout environmental samples that contain solids, including sediments, adds additional levels of analytical difficulties in their effective extraction and new sample matrix interferences. QuEChERS (Quick, Easy, Cheap, Effective, Rugged, and Safe) has become a very popular extraction and cleanup technique for the analysis of multiresidue pesticides in agricultural and food samples. Applying the same principles to overcome similar challenges in PPCP analysis in solid environmental samples is demonstrated in this article.

Following decades of research, evidence of the human microbiome’s importance in maintaining overall health and well-being has become evident, spawning a multimillion-dollar industry. A wide range of products aimed at repairing and maintaining a healthy microbiome are now available, with many focusing on prebiotics.

Researchers have analyzed sediment core from a lake located in the northern foothills of Alaska’s Brooks Range to investigate the Beringian standstill hypothesis (BSH) of human migration into the Americas.

Thermo Fisher Scientific has announced the opening of its Customer Solution Center in Delhi, India.

From ghost peaks to baseline interferences, analytical laboratories deal with several challenges in their everyday work. Tips for Addressing Common Problems with LC Analysis offers laboratories some practical advice for dealing with common analytical problems and suggests using ultrapure water is a key strategy.

Wouldn’t it be nice if a single generic high performance liquid chromatography (HPLC) method could be used for all small molecule drugs - not only for potency assays but also for ICH-compliant stability-indicating assays?

We have been working to develop the use of liquid chromatography–triple quadrupole–mass spectrometry (LC–MS/MS) for quantification of intact proteins from biological fluids.

From its development in 2016, the liquid-electron ionization (LEI) LC–MS interface has demonstrated a high versatility, offering the identification advantages of library-searchable, electron ionization (EI) spectra from samples in a liquid phase.

In this study of pesticides in spinach extract, the use of GC×GC–TOF-MS is demonstrated as a methodology to overcome matrix interferences and quickly quantify suspected contaminants. The approach also allows nontargeted analysis using a single sample injection.

For lurasidone treatment adherence testing, an untargeted high-resolution mass spectrometry method was employed, using known positive human urine samples to identify the lurasidone metabolites and their relative abundance in urine.

A novel mass spectrometry-based flavonoid profiling workflow is applied to characterize and structurally annotate a large number of unknown flavonoids in fruit juice and vegetable juice samples.

We present a brief preview of this year’s ASMS conference, taking place June 2–6, 2019, in Atlanta, Georgia.
