Invented by J. Phillips in 1989, comprehensive GCXGC has strong chromatographic resolving power; from its original petrochemical applications it has been extended to many others. However, coelutions with matrix peaks are often observed and a higher separation power is required.

Comprehensive GC×GC(MS) and LC×LC(MS) are chromatographic hyphenation methods providing the users with extremely large peak capacities.
