Select-eV: Increasing dimensionality in GC×GC–TOF MS
contributed by Markes International Ltd |
Introduction
Comprehensive two-dimensional gas chromatography with time-of-flight mass spectrometry (GC×GC–TOF MS) offers greatly enhanced peak capacity, through the coupling of two columns of different selectivity, as well as highly sensitive detection and definitive mass spectral identification of trace-level analytes.
