Here, a procedure is described for preparing polydisperse polymer standards to validate the accuracy of any SEC method for aqueous or organic mobile phases. This approach can be used for all calibration procedures with the exception of online light scattering and viscometric detection.

I always think of a conference presentation to be like a rock band concert. Sure, the band is going to play some of their biggest hits, but they also want to propagate their new stuff. More importantly, they want to put on a show so that people are entertained. I do think there should be more emphasis on entertaining the audience during oral presentations.

A new year means a fresh start. Incognito suggests some resolutions to help chromatographers succeed in 2018.

Researchers from the Liverpool School of Tropical Medicine and the University of Warwick have conducted a pilot study to assess the viability of a GC–IMS for the analysis of volatile organic compounds (VOCs) in exhaled breath for the diagnosis of bacterial respiratory tract infections (RTIs) in hospital patients.

Researchers from the Harbin Institute of Technology, Harbin, China, have developed a simple method for the extraction of organochlorine pesticides (OCPs) from river water samples using magnetoliposomes as adsorbents and gas chromatography tandem mass spectrometry (GC–MS/MS).

On Wednesday, January 17, Francois Huby of The Dow Chemical Company will present a talk titled “Comparative Evaluation of ‘Carbon Centric’ Gas Chromatography Detectors for Volatile Organic Compounds Analysis.” The presentation is scheduled to take place at 10:55 a.m. in Room 372 D.

Sometimes troubleshooting a separation can rely upon the end user spotting subtle clues within the chromatogram, and at other times the visual signs can be much more obvious. To start the New Year, I wanted to share some of the most common issues that we see with peak shapes in gas chromatography in the hope that if you spot some of these in your own work, you may be able to intercept problems and deal with them more effectively.

Two things were surprising about some recent research we reported. First, with regard to chemically impaired groundwater quality, it may not always be the chemicals that are most worrisome for human health impacts. Second, the primary methodology we used in that work for microorganism identification, matrix-assisted laser desorption–ionization mass spectrometry (MALDI-MS), is a vastly underappreciated tool, especially outside the clinical realm in areas such as environmental monitoring.
