A GCxGC chromatogram of oil found on a rocky beach can reveal that the oil lost 35 percent of its naphthalene via evaporation, while 10 percent of the compound dissolved in water.
En este trabajo se muestra como el uso de un detector especifico acoplado a la GCxGC permite alcanzar una separacion optima, siempre y cuando se cuente con una combinacion apropiada de columnas de separacion y un detector conforme al tipo de moleculas que se desee analizar.
A LECO Pegasus 4D GCxGC TOF/MS equipped with an Agilent 6890 GC and 7683 autoinjector was used to determine pesticide recoveries and levels of incurred pesticides in tobacco.
Agilent was the first vendor to release a commercial a GCxGC system in 2002.
The MS system offers GCxGC with all three ionization modes to produce high-resolution accurate-mass spectra.
We analyzed some of this oil with advanced technology in my lab called comprehensive, two-dimensional GCxGC gas chromatography (see Page 16).
Thermo Electron released the Trace GCxGC solution, calling it the first truly integrated system for comprehensive GCxGC.
Once again, biomarkers revealed by GCxGC showed that the oil in the sediments matched the oil floating on the sea surface, the oil leaking out of the seeps, and the oil extracted from the subseafloor reservoir.
The Editors' Choice Silver Award at the 59th Pittsburgh Conference on Analytical Chemistry and Applied Spetroscopy (Pittcon) in March 2008 went to a product that utilizes a new method for coupling capillary columns in gas chromatography (GC), GCxGC, and capillary zone electrophoresis (CZE): the Meltfit One, from NLISIS Chromatography, Veldhoven, The Netherlands.
GCxGC separates the sample using two coupled columns and a modulator interface that quantitatively transfers and compresses the sample to the second column, resulting in improved separation, sensitivity and reproducibility.
The purchase of new equipment for two-dimensional gas chromatography coupled to a mass spectrometer (GCxGC / TOFMS or GCxGC / Q-TOF), hereinafter referred to as "equipment", are included:
