Chromatography

The following list briefly explains the principle of some of our chromatography methods.
In addition, typical areas of application are presented as examples:
 

GC-MS

  • The combination of gas chromatography (GC) and mass spectrometry (MS) allows the separation of vaporisable substance mixtures and the identification of individual organic components on the basis of the mass spectrum. Coupled with a vapour space injector or a thermodesorption device, the field of application is extended to solid or non-evaporable samples.
  • Fields 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 e.g. from materials of the car interior, monitoring of MAK limits by analysis of air samplers.


High-performance liquid chromatography HPLC

  • HPLC is used primarily to separate and quantify polar, non-volatile substances and identify them by comparison with the retention times of a reference sample. HPLC is also suitable for the analysis of volatile substances in a water matrix or buffer solution.
  • Fields of application: Determination of aldehydes and ketones in materials of the automotive interior.
