3M, the science-based technology company, has commissioned the National Institute for Bioprocessing Research and Training (NIBRT) to conduct in-depth research into their Emphaze AEX Hybrid Purifier, a single use plug and play filter matrix.

Agilent Technologies has awarded Dwight Stoll an Agilent Thought Leader Award in support of his research applying two‑dimensional liquid chromatography (2D‑LC) to biopharmaceutical analysis.

Incognito delves into some statistics on chromatography research, and is unsettled by what he finds.

An autosampler for a standard gas chromatography (GC) or GC–mass spectrometry (MS) system was adapted to perform simple static headspace sampling, instead of using a separate, and potentially more complicated, headspace sampling unit.

A preview of HPLC 2017, which will be held from 18 to 22 June 2017 at the Prague Congress Centre, Prague, Czech Republic.

Novel psychoactive substances pose a major challenge for forensic toxicology and drug-seizure laboratories because of the scale and speed at which these new “designer drugs” are entering the market. To keep pace with the threat, laboratories require robust full-scan detection techniques capable of both targeted drug screening and the identification of unexpected compounds too. Here, a full-scan gas chromatography (GC) coupled to high-resolution accurate mass (HRAM) approach for the profiling of known and unknown drugs of abuse is presented.

I guess we have all had the issue at some time or other. A blank injection of eluent (or a zero volume dummy injection) gives rise to discreet peaks on the chromatographic baseline which may interfere with analyte peaks or increase the complexity of the chromatogram obtained, especially when performing trace analysis.chromatogram obtained, especially when performing trace analysis. Of course this is an undesirable situation and one which can be difficult to understand or troubleshoot as, if we didn’t inject anything, how on earth do we end up with discrete beaks in the blank chromatogram? The secret to understanding the phenomenon lies in understanding the mechanisms of gradient of HPLC.

This is the sixth instalment of a series of articles exploring current topics in separation science that will be addressed at the HPLC 2017 conference in Prague, Czech Republic, from 18–22 June.

As part of the Earth Day celebration in Dallas, Texas, last month, the Collaborative Laboratories for Environmental Analysis and Remediation (CLEAR) at U.T. Arlington hosted the first annual Responsible Shale Energy Extraction (RSEE) symposium (www.shalescience.org). We had an exceptional range of speakers who conveyed all sides of the issue, including U.S. Secretary of Energy Rick Perry and atmospheric scientist Dr. Katherine Hayhoe from Texas Tech University, one of Time’s top 100 most influential people. We had representatives from major oil producers, environmental groups, land management groups, water recycling service companies, and scientists conversant on many key issues related to unconventional oil and gas (UOG) extraction. Even though we have been very involved in this conversation for the past several years, several points stood out.

Several variables can be used to change selectivity in a liquid chromatography (LC) separation. Here we compare the variables in an effort to prioritize which experiments will be most effective.

In this instalment, John Hinshaw presents an annual review of new developments in the field of gas chromatography (GC) seen at Pittcon 2017 and other venues in the past year.

The International Symposium for High-Performance Thin-Layer Chromatography (HPTLC 2017) will take place in Berlin, Germany, 4–8 July 2017.
