Shimadzu Multi-Dimensional GC (MDGC) are ideal for complete separation and quantitation of specific compounds in difficult matrices such as petroleum products and flavors/fragrances. The system uses columns with different separation characteristics to achieve highly accurate separation of target compounds.
The multi-dimensional GC/GCMS system uses two columns with different separation characteristics to achieve high-resolution analysis not possible with a conventional single column. Components insufficiently separated as they pass through the first column (1st column) are introduced ("heart-cut") into a second column of a different type (2nd column) to separate their analytes.
