GCXGC-TOF

WA Organic and Isotope Geochemistry Facility

Manufacturer: LECO
Model: Pegasus 4D
Year: 2013
Building: 500
Room: 322

Uses two different GC columns to perform comprehensive two-dimensional gas chromatography (e.g. separation by boiling point and then polarity). Allows separation of compounds which would co-elute in first dimension, far greater peak resolution for complex mixtures.

Two different GC columns.
Cryogenic modulator to focus eluent from primary column onto secondary column.
Rapid TOF-MS detector allows mass spectral identification.
Chroma TOF software produces comprehensive 2D chromatographs.
