In this eBook partnership with LCGC, explore how Gas Chromatography can help laboratories characterize cannabis and analyze terpenes using headspace solid-phase microextraction, and more. From 31 October 2019.

This document is intended to provide an introduction to LECO's comprehensive two-dimensional gas chromatography (GCxGC) systems. Suggestions and recommendations are intended to help new users become familiar with the technique and how the ChromaTOF software may be utilized. LECO Ref. #209-066-011

Heavy Fuel Oil (also "bunker oil" or "residual fuel oil") is a complex mixture of petroleum hydrocarbons formed as the remnant of distillation and cracking processes. Often used by the shipping industry, heavy fuel oils have becoming more regulated for lower sulfur content. 

Comprehensive two-dimensional gas chromatography paired with high-resolution time-of-flight mass spectrometry and multiple ionization modes can provide a full characterization of the volatile and semi-volatile compounds in this complex mixture.

Frank Dorman [Penn State University] discusses how time-of-flight mass spectrometry can be used to study fluids involved with hydraulic fracturing, to identify environmental contamination concerns. Presented 19 July 2012.

Chemical constituents on their wings provide cicadas with water resistance as well and antimicrobial, anti-reflective, and self-cleaning functions. In this study, the wing chemicals of two cicada species were examined using the Pegasus® BT 4D GCxGC-TOFMS system and analyzed through the ChromaTOF® software.
