Discover some of our methods.

ASO Magnifier


The combination of gas chromatography (GC) and mass spectrometry (MS) allows the separation of vaporizable substance mixtures and the identification of individual organic components based on the mass spectrum. Coupled with a headspace injector or a thermal desorption device, the area of application is expanded to include solid or non-vaporizable samples.

​Areas of application

  • Qualitative and quantitative analyses of gas or liquid samples, such as solvents in paints or identification of unknown compounds in oil samples

  • Determination of the emission of organic compounds, for example from materials used in vehicle interiors, monitoring of MAK limit values by analyzing air collectors.

High performance liquid chromatography (HPLC)

HPLC is used primarily to separate and quantify polar, non-volatile substances and to identify them by comparing them with the retention times of a reference sample. HPLC is also suitable for analyzing volatile substances in a water matrix or buffer solution.

application areas

  • Determination of aldehydes and ketones in automotive interior materials

Size-exclusion chromatography (SEC)

Gel permeation chromatography GPC/SEC is used, for example, to separate polymer plastics according to their hydrodynamic radii. This makes it possible to calculate the average molecular weight and polydispersity. In contrast to the viscosity number, GPC offers the possibility of determining the average molecular weight of different polymers, e.g. in mixtures.
