The Development and Evaluation of Non-invasive Methods to Characterise the Disease States of Patients Utilising Selective Discrimination, Gas Chromatography-Mass Spectrometry and Chemometrics
… gas chromatography-mass spectrometry (GC-MS) and chemometrics. The primary analytical technique investigated was GC-Time-of-Flight-MS coupled with headspace solid-phase microextraction (HS-SPME-GC-ToFMS). A robust and sensitive method was developed by optimisation of all sample analysis …

Improving Detection and Identification Methods for Volatile Organic Explosives
… gas chromatography-mass spectrometry (GC-MS) system was also tested, however due to several issues presented the instrument was not able to perform headspace analysis. Instead, a benchtop GC-MS and a two dimensional gas chromatograph (GC×GC) coupled to a time of flight mass spectrometer …

Measurement of lipid peroxidation in biology models using gas-chromatography-aass spectrometry
… with time-of-flight mass spectral capabilities (GC-TOFMS) and were found to include the lipid peroxidation product hexanal. The pro-oxidant cumene hydroperoxide elevated the levels of these lipid peroxidation products, whereas the anti-oxidant butylated hydroxy toluene (BHT) impaired their …

Study of Polyaromatic Hydrocarbons Emitted in the Fly Ash from Coal Combustion in a Fluidized Bed Combuster
… the fly ash. Once the extraction was completed, GC/MS in the selective ion monitoring (SIM) mode was used to analyze the extract. The other method used to extract the PAHs from the fly ash was the thermal extraction method. This method allows direct analysis of the PAHs without any use of a …
