Gas Chromatography Mass Spectrometry
The combination of gas chromatography (GC) and mass spectrometry (MS) enables the separation of vaporizable substance mixtures and the identification of individual organic components based on their mass spectrum. Coupled with a headspace injector or a thermal desorption unit, the application range extends to solid or non-vaporizable samples.
Applications
- Analysis of Solvents and Lacquer
- Identification of Unknown Compounds
High-Performance Liquid
Chromatography
High-Performance Liquid Chromatography (HPLC) is primarily used to separate, quantify, and identify polar, non-volatile substances by comparing them with the retention times of a reference sample. HPLC is also suitable for the analysis of volatile substances in an aqueous matrix or buffer solution.
Applications
- Determination of Aldehydes and Ketones in Automotive Interior Materials
Gel Permeation Chromatography GPC
With Gel Permeation Chromatography GPC/SEC, polymeric plastics, for example, are separated according to their hydrodynamic radii. This enables the calculation of average molar masses and polydispersity. Compared to the viscosity number, GPC offers the possibility to determine the average molar masses of different polymers, e.g., in mixtures.
