The headspace of these coffee beans was extracted using a 65 μm PDMS/DVB solid-phase S4 microextraction (SPME) fiber at 60 oC for 10 min. Separations of the headspace extracts were performed on GC×GC-TOFMS configured with an Agilent 6890N GC (Agilent Technologies) and a Article Title: Simultaneous discovery of compounds dominated by either molding kinetics or geographical region of origin for moisture damaged cacao beans using orthogonally applied tile-based fisher ratio analysis of GC×GC-TOFMS data. Article Snippet: Herein, two “orthogonal” characteristics of moisture damaged cacao beans (temporally dependent molding kinetics versus the time-independent geographical region of origin) are simultaneously analyzed in a comprehensive two-dimensional (2D) gas chromatography time-of-flight mass spectrometry (GC×GC-TOFMS) dataset using tile-based Fisher ratio (F-ratio) analysis.. Cacao beans from six geographical regions were analyzed once a day for six days following the initiation of moisture damage to trigger the molding process.. Thus, there are two “extremes” to the experimental sample class design: six time points for the molding kinetics versus the six geographical regions of origin, resulting in a 6 × 6 element signal array referred to as a composite chemical fingerprint (CCF) for each analyte.

Article Snippet: Accurate analyte peak detection from the background noise is a fundamental step in data analysis.. Often this is initially 6 performed on the total ion current chromatogram (TIC), which is the sum signal from all mass spectral channels.. Despite detecting 7 many of the most abundant peaks within a chromatogram, a large fraction of peaks remain undetected in the standard TIC due to their 8 signal being below the limit of detection. Article Title: Enabling cuboid-based fisher ratio analysis using total-transfer comprehensive three-dimensional gas chromatography with time-of-flight mass spectrometry. Article Snippet: Comprehensive three-dimensional (3D) gas chromatography with time-of-flight mass spectrometry (GC3-TOFMS) is a promising instrumental platform for the separation of volatiles and semi-volatiles due to its increased peak capacity and selectivity relative to comprehensive two-dimensional gas chromatography with TOFMS (GC×GCTOFMS).. Given the recent advances in GC3-TOFMS instrumentation, new data analysis methods are now required to analyze its complex data structure efficiently and effectively.. This report highlights the development of a cuboid-based Fisher ratio (F-ratio) analysis for supervised, non-targeted studies.
