Introduction of a Multidimensional GC SystemAnalysis of 37 FAMEs using 6 Types of Capillary Columns

Introduction

Accurate analysis of trace-level compounds in samples with complex matrices, such as refined petroleum products, flavor and fragrance formulations, and environmental samples, is not easy due to the difficulty in completely separating the target compounds from other compounds in the matrix. In the past, the approach to resolving this issue was to investigate the effectiveness of sample pretreatment procedures, separation columns and selective detectors, etc. However, with the recent adoption of multidimensional GC (MDGC) systems in which high resolution is achieved relatively easily, high-accuracy analysis has become possible, samples that contain trace-level analytes, such as those mentioned above. An MDGC system is a GC system incorporating two types of columns, so that components that cannot be separated by the first column are heart-cut and introduced into the second column for detailed separation. This Application News introduces such an MDGC system.
