Renaissance of the Multidimensional GC Method

摘要

Shimadzu (Germany) introduces the new multidimensional MDGC-2010. The system serves a wide range of applications in environmental and food analysis or other complex sample type analyses. This multiple heart-cut multidimensional system was particularly designed for the transfer of co-eluting peaks to a second column ("cut") and makes quantitation very easy. The MDGC-2010 represents the renaissance of the multidimensional GC method. It applies the well-known Deans Switch technology, but in a totally different way than in the past. Using different restrictors, the pressure at the end of the first column always remains constant, whether or not a cut is used. It is a real breakthrough that the user may perform as many cuts as required without any shifts of retention time and with excellent precision of the retention times.
