Cromatografia gasosa bidimensional abrangente (GC × GC)

Comprehensive Two-Dimensional Gas Chromatography Coupled to Time of Flight Mass Spectrometry: New Biomarker Parameter Proposition for the Characterization of Biodegraded Oil

Cromatografia gasosa bidimensional abrangente acoplada à espectrometria de massas por tempo de voo (GC×GC-TOFMS) é uma técnica apropriada para a elucidação da composição molecular de amostras petroquímicas, como óleos biodegradados. Biomarcadores foram separados, identificados e razões de biomarcadores convencionais foram determinados usando cromatografia gasosa acoplada à espectrometria de mas...

GC×GC Handbook Fundamental Principles of Comprehensive 2D GC

Grigg GC

1. Fishes in Antarctic seas live at a temperature lower than that at which most other poikilotherms remain active. 2. Hematocrit, absolute oxygen capacity and oxygen equilibrium curves were determined for whole blood from each of four related species of Antarctic fishes. These parameters were related to the habits and activity of each species. 3. Temperature increase was found to have a marked ...

Comprehensive two-dimensional gas chromatography--GC x GC.

The biggest limitation to conventional gas chromatography (GC) is limited peak capacity, making the analysis of complex mixtures a difficult or even impossible task. Comprehensive two-dimensional gas chromatography (GC×GC) significantly increases peak capacity and resolution, improves sensitivity and generates structured 3D chromatograms. This is achieved by connecting two columns coated with d...
