Multidimensional Gas Chromatography

Gas chromatography experts rely on sharp peaks and baseline resolution to provide accurate answers. To perform chromatographic analysis of real-world samples, analysts often must deal with either complex sample types such as essential oils and petroleum fractions, or complex matrices like biological fluids, foods, sludge, or polymers. Once the sample has been prepared for analysis, separation of all the individual compounds present by means of a single chromatographic separation can be challenging due to the compounds having different ranges of polarity, boiling point, solubility, MW, and concentration. Therefore, in order to achieve the separation needed for these types of samples, it is necessary to go beyond using a single chromatographic dimension and use multidimensional techniques. Until now, multidimensional GC required the use of a dedicated system with two GCs coupled to each other.

GERSTEL offers the most advanced systems for performing multidimensional gas chromatography either for routine analysis as well as for complex problem solving.

See a recent article in LC/GC's digital magazine "The Column" describing the latest advances in multidimensional GC for flavor analysis.
