Highly repeatable fragmentation of the compounds into the ion source is one of the major advantages of using gas chromatography coupled with electron ionization mass spectrometry (GC–EI-MS) for the analysis of volatile and semivolatile compounds. The generation of intense and diagnostic fragmentation when the ionization is performed at 70 eV has been used for the creation of many established databases-enabling the analyte identification process.

The House of Lords EU Home Affairs Sub‑Committee has highlighted the risk of losing access to key sources of Horizon 2020 funding in a “no-deal” scenario and called on the Government to confirm that the UK will seek full association to the next phase of the programme, “Horizon Europe”.

Shimadzu employees have volunteered to reforest an area in the Duisburg city forest (Germany) planting 1500 new trees and contributing to the long-lasting woodlands development.

Restek Corporation and LECO have agreed an expanded collaboration that will allow LECO customers access to a core set of Restek consumables.

Evolve or die!

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.

This is the first in a series of articles exploring current topics in separation science that will be addressed at the HPLC 2019 conference in Milan, Italy, from 16–20 June.

The “5th Workshop on Analytical Metabolomics” will be held in Thessaloniki, Greece, from the 13–17 May 2019. Here is a sneak preview of what attendees can look forward to.

Peter Schoenmakers, a professor of analytical chemistry at the University of Amsterdam, received the Chromatography Forum of the Delaware Valley Dal Nogare Award on Monday, March 18, at Pittcon 2019, in Philadelphia Pennsylvania.

As we close in on a little more than a month to go before the 43rd International Symposium on Capillary Chromatography and the 16th GCxGC Symposium (ISCC & GCxGC 2019; www.isccgcxgc.com), May 12 – 17 in Ft. Worth, Texas, my excitement burgeons. All of the groundwork has been laid to provide forums for presenting and discussing the latest advances in capillary and comprehensive separations science.

The most common method of pesticide extraction for food matrices is QuEChERS. But, is there a better way? This LCGC ebook on Improving Extraction Processes and Sample Preparation in Food Analysis talks about the use of extraction technologies in food analysis and explores how Energized Dispersive Extraction (EDGE®) has revolutionized sample extraction.

Our annual review of new liquid chromatography columns and accessories.

New HPLC and MS systems: A review of instrumentation trends and the current market along with new instruments, modules, chromatography data systems, and related software.

We provide a succinct explanation of electron ionization for GC–MS and illustrate the fundamentals of ion formation.

The meaning of the terms raw data and complete data are explored. One term is from EU GMPs and the other is from US GMPs. Do they mean the same thing?

How well do Gaussian-shaped profiles represent injected solute peaks after they are eluted through a chromatographic column? This question is explored along with a discussion of moment analysis for determining retention time, variance, and shapes of peaks.

The field of sample preparation is undergoing revolutionary change, largely governed by the need for miniaturization while maintaining high selectivity and high analyte enrichment. How up-to-date are you in the advances of sample preparation for chromatographic analysis?

In this study, the analysis of contaminants found in environmental waters and originating from personal care products is addressed using metalorganic frameworks (MOFs) in combination with liquid chromatography (LC). This work expands the use of MOFs from gas chromatography to LC and also meets the requirements of green analytical chemistry.

Nanomaterials are extremely useful as sorbents for sample preparation, because of their varied morphologies, high surface area, surface-tovolume ratio, porosity, and ability to interact with samples in a variety of ways. Here, we review how nanomaterials are being used in a variety of sample preparation techniques, such as dispersive solid-phase extraction (dSPE), solid-phase microextraction, stir-bar sorptive extraction, and matrix solid-phase dispersion.

A simple, fully-automated method is proposed to analyze extractables and leachables-compounds that are released from packing materials into drugs during storage-using SPME-GC×GC–MS. This method avoids the use of sample preparation solvents and reduces sample handling, and is ideal for routine use in quality control.

Crude (4-methylcyclohexyl)methanol (MCHM) is a chemical contaminant that must be monitored in fresh water environments, because of significant health risks to surrounding human populations. A new method for MCHM analysis was developed using solid-phase microextraction (SPME) and thin film microextraction (TFME) combined with GC–MS. Both methods achieved limits of quantitation lower than standard methods using SPE.
