Incorporation of Gas Chromatography–Mass Spectrometry into the Undergraduate Organic Chemistry Laboratory Curriculum

Journal of Chemical Education, 2012
Gas chromatography–mass spectrometry (GC–MS) is a powerful analytical tool for detection, identification, and quantification of many volatile organic compounds. However, many colleges and universities have not fully incorporated this technique into undergraduate teaching laboratories despite its wide application and ease of use in organic chemistry. In

Environmental petroleum pollution analysis using ramped pyrolysis-gas chromatography–mass spectrometry

Organic Geochemistry, 2018
Abstract In response to the Deepwater Horizon oil spill, critical research has tracked the changes in petroleum hydrocarbons with environmental weathering. There are limitations, however, whereby single analytical techniques cannot always identify the wide breadth of petroleum and petroleum-derived compounds. We explore the analytical capabilities of

Determination of JP-8 components in soils using solid-phase microextraction–gas chromatography–mass spectrometry

Fuel, 2008
Abstract Jet Propellant-8 (JP-8) is a military fuel associated with a large percentage of chemical exposures documented by the US Department of Defense. A fast and sensitive solid-phase microextraction–gas chromatographic–mass spectrometric (SPME–GC–MS) method has been developed for the determination of 34 ‘marker compounds’ found in JP-8.

Cloud-Point Extraction Combined with Thermal Degradation for Nanoplastic Analysis Using Pyrolysis Gas Chromatography-Mass Spectrometry.

Analytical Chemistry, 2019
The contamination of micro- and nanoplastics in marine systems and freshwater is a global issue. Determination of micro- and nanoplastics in the aqueous environment is of high priority to fully assess the risk that plastic particles will pose.
