Application Data from Recent Oil Spill to Help Determine the Environmental Impact
 13 Aug 2010: LECO has released a new application note highlighting the analysis of two petroleum samples obtained from the recent oil spill in the Gulf of Mexico. Using a Pegasus® 4D GCxGC-TOFMS with GERSTEL autosampler and ChromaTOF® software, the analyst was able to resolve and identify an unprecedented number of individual components in a single analysis for the ultimate in high throughput.

Analysis of Samples from the Gulf of Mexico Oil Spill by GCxGC-TOFMS
20 Jul 2010: The recent oil spill off the coast of Louisiana, in the Gulf of Mexico, is the largest oil spill in US history. The ability to identify the chemical make-up oil samples from this spill will be an important tool utilized by those responding to this event. This application note demonstrates the ability of LECO's Pegasus 4D GCxGC-TOFMS system to identify a large number of components in a single analysis.

Anti-Doping Control Using Comprehensive Multidimensional Gas Chromatography Time-off-Flight Mass Spectrometry (GCxGC-TOFMS) for Enhanced Detection off Anaboliic Steroids iin Urine
29 Jun 2010: This application demonstrates that steroid screening is improved significantly by GCxGC-TOFMS compared to onedimensional chromatography using GCMS. Excellent calibration linearity for quantitation was achieved for all analytes at greater than 99.9%. Limits of detection at part per trillion levels were calculated from acquired data for all five steroids.

Analysis of Drug Facilitated Sexual Assault (DFSA) Drugs by Gas Chromatography-Time-of-Flight Mass Spectrometry
29 Jun 2010: This poster displays the ability of GC-TOFMS to effectively screen case-study urine samples for the presence of potential DFSA drugs. The use of mass spectral deconvolution algorithms can increase sample throughput by reducing the need for total chromatographic resolution which allows shorter run times. Of the 24 samples analyzed, 16 contained drugs that would be considered potential DFSA drugs.
