The 2018 recipients of the John B. Fenn Award for a Distinguished Contribution in Mass Spectrometry are Gert Von Helden, Martin F. Jarrold, and David E. Clemmer, for their pioneering contributions to the development of ion mobility spectrometry (IMS).

This Monday morning session explores the various issues that arise in the quality control laboratory. Jason Rouse of Phizer, Inc. will chair the session, which will be held in Ballroom 20 BC on the upper level, from 8:30 to 10:30 pm.

This Monday afternoon session will present recent advances in mass spectrometry imaging in plants, animals, and humans. It will be chaired by Shama Mirza of the University of Wisconsin-Milwaukee and will be held in Ballroom 20A from 2:30 to 4:30 p.m.

This second of the two parallel tutorial sessions on Sunday evening includes talks from Gregory Eiden of Pacific Northwest National Laboratory (PNNL) and Jack Beauchamp of California Institute of Technology.

Three one-day short courses will be held on Sunday, June 3, from 9:00 am–4:30 or 5:00 pm. Course registration and badge pick-up is at 8:00 am on Sunday, and lunch and refreshment breaks will be provided.

Specialists in food analysis are increasingly interested in taking advantage of methods that harness the power of ultrahigh-pressure liquid chromatography (UHPLC) and high-resolution mass spectrometry (HRMS). Jon Wong of the Center for Food Safety and Applied Nutrition at the U.S. Food and Drug Administration has been developing such methods for a variety of types of analysis. In this interview, he talks to LCGC about the work to develop these methods and the advantages of their use.

The chemical analysis of organic compounds in environmental samples is often targeted on predetermined analytes. A major shortcoming of this approach is that it invariably excludes a vast number of compounds of unknown relevance. Nontargeted chemical fingerprinting analysis addresses this problem by including all compounds that generate a relevant signal from a specific analytical platform and so more information about the samples can be obtained. A DHS−TD−GC−MS method for the fingerprinting analysis of mobile VOCs in soil is described and tested in this article. The analysis parameters, sorbent tube, purge volume, trapping temperature, drying of sorbent tube, and oven temperature were optimized through qualitative and semiquantitative analysis. The DHS−TD–GC−MS fingerprints of soil samples from three sites with spruce, oak, or beech were investigated by pixel-based analysis, a nontargeted data analysis method.

Metabolomics, a word coined in 1998, is the study of small molecules (that is, organic chemicals with a molecular weight of 50–2000 Daltons) present in a given biological fluid, tissue, organ, organism, and environment at a given time. Using the power and high throughput of analytical platforms, such as mass spectrometry (MS) or nuclear magnetic resonance (NMR) spectroscopy, metabolomics promises to be a cornerstone in innovations and discoveries in the areas of medicine, agriculture, biomedical, space, and environment. Thus, science, technology, engineering, and mathematics (STEM) graduates and doctorates who interface with analytical chemistry need to prepare for the challenges of academia or industry as metabolomics research takes a centre stage in this big data era.

Peak intensity enhancement is one highly desirable outcome of comprehensive two-dimensional gas chromatography (GC×GC). When coupled to mass spectrometry (MS), such enhancement is usually achieved with a thermal modulator using a technique called cryogenic zone compression (CZC). Differential flow modulation is a simple and cost-effective alternative to thermal modulation, but the requisite high flow rates are generally perceived as being incompatible with most (electron ionization [EI] and chemical ionization [CI]) mass spectrometers. The past decade has witnessed resurgent interest in coupling GC to atmospheric pressure chemical ionization (APCI), which requires high gas flows to assist ionization. This article reports on the modification of a GC–APCI system with a flow modulator and evaluates its potential to enhance the sensitivity towards selected trace organics.
