GC x GC is a rapidly growing technique for the analysis of complex samples. Because GC x GC is both a qualitative and quantitative technique, most GC applications can be accomplished using GC x GC.
Some of the main areas of GC x GC applications are:
Petroleum Liquids
Only 10% of late-eluting and semi-volatile components of hydrocarbon mixtures resolve by conventional (“one-dimensional”) GC, whereas 90% or more resolve using GC x GC. Industrial diagnostics and catalytic processes are also well characterized by GC x GC analysis. In all cases, GC x GC provides the best chemical group information available.
Flavors
Flavor extracts used in consumer products, and tobacco in cigarettes are subject to stringent regulatory controls. GCxGC helps fast moving consumer goods industries separate complex mixtures of volatile and non-volatile components in order to meet safety and quality assurance controls.
Fragrances & Perfumery
Fragrance creation and quality assurance of raw ingredients consist of the separation, identification, and quantification of many components, including allergens. GC x GC provides the best known methods for detecting trace components in flavor and fragrance samples.
Metabolomics
GCxGC provides a powerful technique for resolving thousands of low molecular weight metabolites in biological fluids, from cytoplasm extracts to human breath, blood extracts, and others fluids. GCxGC can fight disease, assist in drug R&D, and support clinical studies and toxicology.
Environmental
GCxGC resolves most co-eluents, late-eluting components and known active components in food and soils samples contaminated with pesticides, PCBs and dioxins. It is also useful for identifying isomers that cannot be distinguished by MS detection. GC x GC provides the greatest immunity to interferences in environmental analysis.
Forensics
GCxGC analysis of fire debris permits ready separation and identification of many fire accelerants and plastic and wood pyrolysates.
GCxGC is also appropriate for the following applications:
- Industrial Process Diagnosis
- Catalysis
- Soils & Sediments
- Chemical Warfare Agents
