Petroleum Analysis

Batch Analysis of Oxygenated Components in Gasoline

With gasoline, a large number of hydrocarbon peaks are eluted, making it difficult to completely separate oxygenated compounds, such as the alcohols that have been added in recent years, using GC-FID. Improving separation using MDGC analysis enables the analysis of components for which separation and quantitation would be difficult using conventional FID.

The analysis of the 13 components specified by ASTM D 4815-99*
is described below.

Fragrance Analysis

Batch Analysis of Fragrance Components in Essential Oil

Aromatic analysis, in which large numbers of matrices are contained in the samples, is a field where MDGC analysis demonstrates its effectiveness. Combining nonpolar and polar columns enables the separation of aromatic components and impurity substances. Also, because no fatty acid esters with high boiling points are introduced into the polar column, the analysis time is reduced.

Environmental Analysis

Separation and Quantitation of Substances in River Water that Cause Mold Odor

In the analysis of substances in water that cause mold odor, because the concentration is low and there is a large number of matrices, the quantitative results obtained with GCMS contain large errors. In the example shown below, the peak for geosmin, which is insufficiently separated with conventional analysis, is completely separated.
