Because not all laboratories have UHPLC systems, reverse scaling of methods from UHPLC to HPLC is often needed, particularly in the pharmaceutical industry. The use of superficially porous particles can facilitate this process.

This article, the first in a series on chromatography fundamentals, discusses the cornerstone of all chromatographic techniques-the distribution or coefficient-and its influence on liquid chromatographic separations.

A summary of the findings presented at the HPLC 2017 Jeju conference, reviewing how they fit into overall liquid-phase separation trends and the outlook for the future of these technologies

Gas chromatography makes use of a wide variety of detection methods. In addition to the most often used flame-ionization detection (FID), electron-capture detection (ECD), thermal conductivity detection (TCD), and mass-selective detection (MSD), the list of other detection methods is long. They really shine when deployed properly, but their properties and applications can be a bewildering alphabet soup. This instalment presents a compendium of gas chromatography (GC) detection methods, both past and vanished as well as those that are current and relevant to today’s separation challenges.

The 2017 Chromatography Forum of the Delaware Valley Dal Nogare Award will be presented Monday morning at Pittcon 2018 to Professor Robert Kennedy from the University of Michigan. The award will be presented by Mary Ellen McNally of EI DuPont de Nemours and Company.

This symposium will honor Zachary Breitbach of AbbVie, the winner of the 2018 Satinder Ahuja Award for Young Investigators in Separation Science. This award is given by the Subdivision of Chromatography and Separations Chemistry of the Analytical Division of the American Chemical Society.

In this Tuesday morning symposium, speakers will present novel analytical strategies focused mainly on real-time, in vivo, and in situ tissue analysis.

The first presentation in this Tuesday morning session will be given by Tadeusz Gorecki of the University of Waterloo and is titled “Comprehensive Multidimensional Separations: Can They Get Better?” Gorecki will discuss both GCxGC and LCxLC separations and will present examples of both approaches.

This Wednesday afternoon session was organized by Gregory D. Smith of the Indianapolis Museum of Art at Newfields and covers the latest chromatographic, mass spectrometric, and spectroscopic methods of analyzing natural and synthetic dyes in museum textiles to determine the dye sources, technology, history, and condition of these artifacts.

Eight presentations comprise this Wednesday afternoon session on gas chromatography/mass spectrometry – environmental analysis.

This Thursday afternoon session features eight presentations on the topic of liquid chromatography used in bioanalytical analysis.

This Tuesday afternoon session opens with a presentation by Joan Stevens of Agilent Technologies, titled “Multiresidue Analysis of Pesticides in Cannabis-Infused Oil and Edibles by Various Extractions and Enhanced Matrix Removal Lipid Cleanup.” Stevens will discuss a method for selectively removing lipids from cannabis-infused food products for the analysis of pesticides.

This Tuesday morning oral session will consist of eight presentations on liquid chromatography and its use in pharmaceutical analysis.

This Tuesday morning symposium, organized by Dwight Stoll of Gustavus Adolphus College, brings together experts in liquid chromatography (LC) to discuss recent advances in two dimensional (2D)-LC separations of small and large molecules. Different perspectives from instrument manufacturers, users in the pharmaceutical industry, and academic laboratories will be presented as well as a discussion on some samples related to pharmaceutical and biopharmaceutical applications.

This Wednesday afternoon organized contributed session, organized by Erik L. Regalado and Christopher J. Welch, will provide an overview of recent developments in fast chromatography from theory to applications including high throughput analysis, second dimension of two-dimensional liquid chromatography (2D-LC), MISER (multiple injections in a single experimental run) techniques, ultrafast LC autosamplers, hyphenation with mass spectrometry, and microfluidic devices.

This Thursday afternoon symposium, organized by Ryan P. Rodgers and Kevin Schug, will address recent analytical advances in the environmental monitoring of petroleum production activities and impact assessment of oil spills. The session will focus on advances in produced water, production chemicals, and oil spill characterization.

The Column spoke to Kirsten Benkendorff, an Associate Professor in Environment, Science, and Engineering and the Co-Deputy Director of the Marine Ecology Research Centre at Southern Cross University in Australia about her work investigating Muricidae molluscs, their use in ceremonial incense and traditional medicines, and the role of chromatography in this research.

Analytica will take place from 10–13 April 2018 at the Messe München, in Munich, Germany. The Analytica conference is Analytica’s scientific highlight 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 big focus this year. This preview will shed more light on what to expect.

Waters Corporation and Malvern Panalytical have announced a co-marketing agreement to advance the analysis of polymers.
