Accurate Mass Spectral Database: Harnessing the Power of High Performance Mass Spectrometry at Long Last
Standard mixtures comprising of alkanes, PAHs, semivolatiles, and pesticides were analyzed using a high resolution time-of-flight (HRTOF) mass spectrometer—Pegasus GC-HRT (LECO Corporation, Saint Joseph,MI)—at 10 spectra-per-second (m/z40–300) in high resolution mode (25,000 at FWHH). The resulting chromatographic peaks were automatically found, deconvoluted, and curated into an Accurate Mass Library (AML).

Analysis of Petroleum Products Using Comprehensive Two-Dimensional Gas Chromatography (GCxGC) with Both Time-of-Flight MS and Flame Ionization Detectors
Several possible configurations were tested to develop a workflow which would allow either subsequent or simultaneous acquisitions of GC×GC TOFMS and FID data on the same GC×GC instrument for petroleum analysis.

Mobility of Aeroallergens in Home: Effect of Location of Air Sampling and Implication for Evaluation of Patient Exposure
The Inspirotec sampler permitted the easy testing of multiple locations within a household. Air sampling simultaneously at 12 locations by other technologies would have been technically challenging. These were run by an untrained operator.

A KNIME Pipeline for the Analysis of GC-MS Data in Metabolomics
A KNIME pipeline was developed to perform pre-processing of GC-MS data in an automated way and applied to a Inflammatory bowel diseases case study

Profiling of metabolomic changes induced by testosterone esters in pig plasma and urine
In this study, metabolic fingerprinting to discriminate between pigs treated with 17ß-testosteron esters and control animals has been investigated. Multivariate statistical analysis showed significant metabolic differences between test and control groups on day 28 after aplication of the testosterone hormonal preparation.
