Analytica 2016 Thursday Afternoon Sessions

A team of researchers from the State Laboratory of Chemo/Biosensing and Chemometrics in China has developed a novel high performance liquid chromatography-diode array detection (HPLC-DAD) method for the identification of six synthetic colours in five beverages.

Jean-Luc Veuthey and Alexandre Grand-Guillaume-Perrenoud reveal the latest developments in supercritical fluid chromatography (SFC) that are bringing the technique back to the limelight.

I often get asked about the other important aspects of “screening” in HPLC, which include the mobile phase composition, gradient parameters and flow rate – so that’s the theme of this installment.

Experienced gel permeation chromatography/size-exclusion chromatography (GPC/SEC) users know that equilibration of the columns takes much longer than the time needed by the pump to produce a constant flow. An analysis in this phase would clearly yield different results from those achieved after complete equilibration of GPC/SEC columns. Furthermore, false but constant flow rates affect the molar masses derived from a GPC/SEC calibration curve. An internal flow marker can help to increase reproducibility and accuracy of GPC/SEC results.

A glimpse of what can be expected at Analytica 2016.

Trajan Scientific (Melbourne, Australia), which develops medical devices as well as analytical systems such as gas and liquid chromatography columns and sample preparation systems, has acquired the business of LEAP Technologies (Carrboro, North Carolina).

A team of researchers has developed a high‑throughput analysis method for 192 diverse pesticides and 51 environmental contaminants 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.

Researchers from the Joint Research Centre of the European Commission have published a case study detailing the characterization of new psychoactive substances using gas chromatography–mass spectrometry, nuclear magnetic resonance, high‑resolution tandem mass-spectrometry, and Raman spectroscopy.

Incognito ponders what it takes to be a “good” analytical chemist. Do you make the grade?

Peter Schoenmakers of the University of Amsterdam has been awarded a prestigious grant worth 2.5 million Euros by the European Research Council to develop new high-performance separation technology. The grant will fund Schoenmakers’s research project “Separation Technology for A Million Peaks” (STAMP).

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.
