Gas chromatography (GC)
Analyte
- Undecomposed vaporizable sample mixtures
- Substances with a boiling point below 400 °C and molecular mass under 500 g/mol
- Gaseous, liquid und solid samples
Equipment
Capillary-Gas Chromatograph (Perkin Elmer)
- GC Clarus™ 690 with Flame ionization detector FID and coupled with Mass spectrometer Clarus™ SQ 8 T with electron impact ionization
Sampling systems
- Automatic liquid sampler
- Headspace Sampler - Turbo Matrix™ 40
- Thermal Desorber - Turbo Matrix™ 350
Targets
- Separation of sample mixtures
- Qualitative and quantitative detection of the single components
- Calibration with reference substance as intern and extern standards
- Identification of substances by comparing unknown spectra with spectra of a mass spectral library
Application examples
- Determination of methyl ester end groups in polyesters after hydrazinolysis
- Investigation of polyester composition after methanolysis
- TVOC-determination of organic emission after VDA277 with Headspace-GC and according to VDA278 by thermodesorption
- Test of epichlorohydrin and by-products in cationic starch
