Gas Chromatography (GC)

Here is some of the most popular content posted on LCGC International this week.

Thermal desorption and gas chromatography-tandem mass spectrometry were used to create a method for detecting airborne polycyclic aromatic hydrocarbon (PAH) samples.

A team of researchers has evaluated approaches in exposome research, highlighting sample preparation, MS-based platforms, and data acquisition strategies.

In Part II of our exploration of splitless injection, we will see that it is a surprisingly complex process, and that it is difficult to understand because we cannot see what is happening during the injection process. For this discussion, we will think of the injection process as beginning with the syringe plunger being depressed and ending with the start of a temperature program in the column oven. In most splitless injections, this process requires 30 s to 1 min. There are several band broadening and focusing mechanisms that affect the peak shapes, widths, and heights resulting from splitless injection.

In a continuation of our Inside the Laboratory interview with Chris Reddy, we asked him about the recent documentary, “Out of Plain Sight,” that featured him and his team’s research.

In the second part of this edition of “Inside the Laboratory,” Christopher Reddy of Wood Hole Oceanographic Institution discusses why comprehensive two-dimensional gas chromatography is the optimal technique for investigating complex mixtures of organic chemicals in the environment.

In this edition of “Inside the Laboratory,” Christopher Reddy of Wood Hole Oceanographic Institution discusses his laboratory’s work investigating oil spills and uncovering dichlorodiphenyltrichloroethane (DDT) deposits on the ocean floor. This interview is part one of three of our conversation with Reddy.

LCGC International sat down with Christopher “Chris” Reddy of Woods Hole Oceanographic Institution, whose research was the basis for a recently released documentary.

Scientists from the China University of Sciences combined magnetic solid-phase extraction (MSPE) with gas chromatography–mass spectrometry (GC–MS) to analyze perfluoro carboxylic acids (PFCAs) in different water environments.

Separation scientists frequently encounter critical pairs that are difficult to separate in a complex mixture. To save time and expensive solvents, an effective alternative to conventional screening protocols or mathematical peak width reduction is called iterative curve fitting.

Messina Institute of Technology scientists used gas chromatography–mass spectrometry (GC–MS) to profile illegal samples of Cannabis sativa L.

LCGC International spoke with Jim Gearing, Associate Vice President of Marketing, Agilent Gas Phase Separations Division; Massimo Santoro, Group Business Development Director at Markes International; Ed Connor, GC Product Manager at Peak Scientific; and Bruce Richter, Vice President of Research & Development at Restek Corporation.

LCGC International spoke to Phil Marriott and Humberto Bizzo about a recent paper they published identifying the incorrect use of retention indices in gas chromatography and how this problem can be rectified in practice.
