GC Troubleshooting in 20 Pictures – Part 2

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.

This article describes the current highlights of using molecular imprinted polymers (MIPs) in sample preparation.

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.

In the testing of six different oat brands, headspace sorptive extraction and comprehensive two-dimensional gas chromatography time-of-flight mass spectrometry (GC×GC–TOF-MS) reveal how various packaging types can affect and alter the oats’ volatile profile, underscoring the potential impact of packaging on food quality.
