GC×GC in Industry

Explore the diverse range of applications for GC×GC within the petrochemical industry—from compositional analysis for robust quality control, to improving sustainability

Comprehensive two-dimensional gas chromatography (GC×GC) gives greater clarity of analyses by revealing ‘hidden’ analytes in complex matrices.

The study of petrochemical composition was one of the earliest applications to use GC×GC. This technique provides a high degree of component separation and useful information on molecular structure through the well-known ‘roof‑tiling’ effect.

This eBook explores the diverse range of applications for GC×GC within the petrochemical industry—from compositional analysis for robust quality control to improving sustainability through the development of novel fuels and recycling procedures.

The eBook comprises the White Papers below:

Characterizing complex petrochemicals using GC×GC–FID
In this white paper, the performance of the INSIGHT-Thermal modulator for the characterization of various petrochemicals is demonstrated—including diesel, crude oil, and vacuum gas oil—with enhanced peak capacity, streamlined control, and ramped cold jet flows to accommodate high boilers (C50+).

Improved characterization of malodors in recycled plastics
Find out how thermal desorption (TD) with GC×GC–TOF MS can be used for comprehensive characterization of volatiles from recycled plastics and how the method is simple to translate to routine screening in QC labs.

Detailed chemical characterization of pyrolysis oils from mixed waste plastic
Discover how GC×GC–TOF MS with thermal modulation was used to provide detailed and sensitive characterization of pyrolysis oil composition to identify possible contaminants and to help refine process design.

[On-Demand Presentation] Improving GC×GC workflows for petrochemical analyses
Until now, the full potential of GC×GC workflows has not been realized, as several challenges persisted in terms of optimization, automation, and data analysis.

This presentation highlights the ongoing efforts to enhance GC×GC workflows for petrochemical analyses by addressing these challenges through novel hardware and software improvements.

Learning Objectives

  • Hear about the latest advances in both flow and thermal modulation.
  • Find out how automated software workflows can speed up data processing.
  • Explore the latest GC×GC applications, including the analysis of sustainable aviation fuels, pyrolysis oils, and much more.

[On-Demand Presentation] How to analyze odors in post-consumer recycled plastics
The global push towards a circular economy has resulted in an increase in the use of recycled materials to reduce waste, with manufacturers being urged to produce or use more post-consumer recycled (PCR) plastics, especially for food and beverage packaging.

However, rigorous quality control (QC) is needed to ensure that recycled plastics do not produce volatile emissions that could be harmful or have a negative impact on the packaged product (e.g., malodors).

In this presentation, we demonstrate how to overcome low sensitivity, poor detection of compounds, and slow processes when analyzing recycled plastics for bad odors.

Learning Objectives

  • Hear about the challenges involved in the analysis of PCR plastics.
  • Learn the basics of GC×GC and what it can offer for odor detection when coupled with thermal desorption (TD) and time-of-flight mass spectrometry (TOF MS).
  • See the technique in action for the analysis of odors from plastic pellets, as well as the identification of potential migrants in bottled water.
  • Hear about our end-to-end workflows for R&D labs and routine screening at production sites.
