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...

Two-dimensional correlation optimized warping algorithm for aligning GC x GC-MS data.

A two-dimensional (2-D) correlation optimized warping (COW) algorithm has been developed to align 2-D gas chromatography coupled with time-of-flight mass spectrometry (GC x GC/TOF-MS) data. By partitioning raw chromatographic profiles and warping the grid points simultaneously along the first and second dimensions on the basis of applying a one-dimensional COW algorithm to characteristic vector...

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 ...
