Retention Times of 209 PCB Congeners Using GCxGC-TOFMS - LECO apps note

In this LCGC International interview with José Fernando Huertas-Pérez who is a specialist in chemical contaminants analytics and mitigation at the Nestlé Institute for Food Safety and Analytical Sciences at Nestlé Research in Switzerland, In this interview we discuss his recent research work published in Food Chemistry on the subject of a method for quantifying multi-residue pesticides in food matrices using gas chromatography–tandem mass spectrometry (GC–MS/MS) (1).

LCGC International sat down with Giorgia Purcaro of the University of Liege to discuss the impact that solid-phase microextraction (SPME) and comprehensive multidimensional gas chromatography (GC×GC) is having on food analysis.

In this LCGC International interview with Philip J. Marriott and Michelle S. S. Amaral from the Australian Centre for Research on Separation Science, School of Chemistry, Monash University, in Clayton, Victoria, Australia, we discuss their recent review published in Analytical Chemistry on the subject of analysis of food contaminants using multidimensional gas chromatography (1).

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.

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.
