Advantages of Two-Dimensional Gas Chromatography

The potential of two-dimensional gas chromatography (GC x GC) for the investigation of complex mixtures of organic compounds is briefly reviewed. Various designs of modulators for GC x GC are considered. Requirements for the equipment necessary for the successful implementation of the GC x GC method are formulated. The main advantages of GC x GC over classical one-dimensional gas chromatography are listed. Typical separation problems that are solvable by GC x GC are considered.
