Shimadzu - Model MDGC/GCMS Series - Multi Dimensional Gas Chromatograph - Brochure

A multi-dimensional GC/GCMS system performs separation using two columns that have different characteristics. The system has a mechanism in which the components that are insufficiently separated in the first column they pass through (the "1st column") are introduced ("heart-cut") to a second, different column (the "2nd column"). This enables analysis with a level of separation that cannot be attained in conventional single-column analysis. In addition, the precise flow-switching technology, which is supported by a high-precision digital flow controller, ensures heart-cut analysis with a high level of reproducibility.
