Analytica 2018

Analytica will take place from 10–13 April 2018 at the Messe München, in Munich, Germany. The Analytica conference is a highlight of Analytica and will take place at the International Congress Center (ICM) from 10–12 April 2018. The increasing digitization in the laboratory and the handling of the resulting flood of data are the big focus this year. This preview will shed more light on what to expect.

Terpenes contribute heavily to the senses of smell and taste and thus are integral to industries like herb and spice producers, essential oil manufacturers, cannabis growers and distributors, breweries, and distilleries, among countless others. Current terpene analysis is performed using gas chromatography–flame ionization detection (GC–FID) and GC–mass spectrometry (MS); however, baseline separation is needed for quantification because many terpenes of interest are isomers, which can lead to relatively long run times. Vacuum ultraviolet (VUV) spectroscopy can spectrally distinguish isomers and quantitatively deconvolve coeluting peaks, allowing for significant reduction in GC run time. This article outlines a method for the analysis of 21 terpenes in a variety of samples with a sub 9-min elution time.

The American Chemical Society (ACS) 2018 National Awards will be presented at a ceremony on March 20 in conjunction with the 255th ACS National Meeting in New Orleans.

I'm often asked to help with the development of column "screening" platforms and automated development systems. While this covers a large amount of analytical science there are some common elements to this type of approach, perhaps the most important of which is column selection. Unsurprising given that "selectivity" is the most powerful tool we have in chromatography and we all know that the best way to optimize selectivity is to choose the most appropriate stationary phase.

In advance of Pittcon 2018, leading scientists-Ronald Majors, Richard Henry, John W. Dolan, Zachary S. Breitbach, and Daniel W. Armstrong-who will be speaking at the LCGC awards symposium give us a preview of their talks.

Despite the theoretical promise of reduced plate heights (h) < 1, most modern UHPLC columns can only deliver plate heights in the range from 1.4 to 2.5. However, improved packing procedures, a better understanding of the colloidal properties of particle suspensions, and the study of the rheological behavior of packed beds and the final bed structure should lead us to practical solutions that can double the column efficiencies.

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.
