(Peabody, Mass. June 7, 2013) -- JEOL USA, Inc. (Peabody, MA) has concluded an OEM agreement with Zoex Corporation (Houston, TX) to offer the Zoex comprehensive two-dimensional gas chromatography (GC x GC) technology with the new JEOL AccuTOF GCV 4G high-resolution time-of-flight mass spectrometer system. 

“We are very excited about the partnership with Zoex. The combination of comprehensive two-dimensional GC with high-resolution, high-sensitivity mass spectrometry is a very powerful platform for the analysis of complex mixtures” says Robert B. Cody, Product Manager for Mass Spectrometry at JEOL USA, Inc. 

The AccuTOF GCV 4G’s unique capability to easily switch between electron ionization (EI) and field ionization (FI) mode combines the power of database searching in EI mode with unambiguous molecular weight information in FI mode. Unlike chemical ionization (CI), field ionization does not require a reagent gas and FI mass spectra are very simple, consisting of molecular ions with little or no fragmentation. Accurate mass measurements can be carried out in either EI or FI mode, or with the optional CI ion source. The AccuTOF GCV 4G is the only mass spectrometer system that offers GC x GC with all three ionization modes: EI, FI, and CI to produce high-resolution accurate-mass spectra.

The combination of Zoex Corporation’s proven thermal modulation technology and GC Image software with the JEOL AccuTOF GCV 4G offers unparalleled analytical performance for complex mixture analysis.

Zoex Corporation 

Zoex Corporation, based in Houston, Texas, USA has driven the commercial development of GC x GC (Comprehensive Two-dimensional Gas Chromatography) from its earliest days in the laboratory of its inventor, the late Professor John B. Phillips, to the present. Comprehensive two dimensional GC is a powerful separation technique that employs unique hardware to concentrate and focus the effluent from a capillary GC column for introduction onto a second capillary column. In GC x GC, the peak capacities of two columns multiply, resulting in enormous resolving power. Zoex supplies Thermal Modulators together with the industry standard GC Image Software for data processing, Zoex continues with its history of supporting the analysis of most complex and demanding gas chromatographic problems.

Today Zoex GC x GC systems are installed throughout the world, and are employed in such applications as petroleum, flavors and fragrances, environmental, forensics, and metabolomics.
