The Column spoke to Noor Abdulhussain from the University of Amsterdam, about her research on 3D-printing in separation science.

The chemical deterioration of historic glass objects on display and in storage in museum collections is a major concern for conservators and curators with the survival of precious historical artefacts in jeopardy.

There are three main sub-species of cannabis—indica, sativa, and ruderalis—but there are hundreds of commercial strains based on these sub-species and their hybrids. Profiling the terpene content in these strains is vital to provide accurate labelling of cannabis-based products, but it can be very challenging. The usual technique for this—one-dimensional gas chromatography (GC)—is not always reliable when it comes to separating the diverse classes of terpenes. This article illustrates how two-dimensional GC (GC×GC) coupled with mass spectrometry (MS) can be used to profile cannabis terpenes with enhanced separation, resulting in the confident identification of terpenes and improved flavour interpretation.

Gel permeation chromatography/size-exclusion chromatography (GPC/SEC) columns are filled with porous particles differing in particle and pore sizes. Typical particle sizes in analytical GPC/SEC range from sub-2-µm particles applied in oligomer and protein separations to approximately 20 µm for separations of ultrahigh molar mass macromolecules (1,2). While the effect of combining columns of different pore sizes has previously been discussed in GPC/SEC Tips & Tricks (3,4), the effect of combining columns of different particle sizes has not been addressed before.

BIA Separations has announced the company has signed agreements with Bioscience companies, GeneX India Biosciences, Chennai, India and IT Technologies (IT Tech), Singapore. Both Companies will act as sole distributors of BIA Separations’ products and services across their respective regions of India, and Singapore and Malaysia.

Researchers have developed and validated a multiresidue method for pesticide and veterinary drug detection in animal feeds using liquid- and gas chromatography with tandem mass spectrometry (LC–MS/MS and GC–MS/MS).

The first to pick up the mantle of The LCGC Blog on behalf of the American Chemical Society Analytical Division, Subdivision on Chromatography and Separations Chemistry, is James Grinias. From coding to circuitry, James expresses the need for electronics to be central to analytical chemistry education. He discusses the critical nature of electronic principles for chromatographers in particular—key to data collection and method design.

Incognito looks to a stellar gathering of scientists from the 5th Solvay Conference in 1927 for inspiration to rejuvinate his mojo in these uncertain times.
