Analysis of Gas Sample Using Single-Oven MDGC

Introduction

A multidimensional GC (MDGC) system is a type of GC system with an integrated switching system which includes two or more columns, so that substances which cannot be sufficiently separated using a single capillary column are heart-cut using flow line switching technology and routed to a separate column with a dissimilar phase, thereby obtaining the required chromatographic resolution. MDGC analysis employing dual ovens for providing freedom in setting column temperatures is now quite common; however, high resolution can also be obtained with a single- oven type system, depending on the complexity of the sample. Here we introduce an example of analysis of a gas sample using a single-oven type MDGC. A switching program can easily be created with special software that can be downloaded from the Shimadzu website free of charge.
