Gas Chromatography (GC)

Gas Chromatography is a physical-chemical separating process both for qualitative and for quantitative analytics of of organic substances. The basic condition for that is an evaporation of the single substances without their destruction. 

GC-equipment Description
MS-detector (mass spektrometry) Identification and assigment of mixtures of unknown substances in e.g. varnishes, samples of natural substances, fragrances and odorous substances
FID (flame ionisation detector) Robust detector for organic substances with high sensitivity (detection limit 1 ng)
Headspace Method for analytics of highly volatile substances
SPME (solid phase micro extraction) Method for analytics of samples with low concentrations

For sample injection, the following systems are present: on-column, SSL (split/splitless), PTV (programmed temperature vaporizer)

High Pressure Liquid Chromatogrphy (HPLC)

The high pressure liquid chromatography is a physical-chemical separating method for qualitative as well as quantitaive analytics of mixtures of substances. In contrast to GC, the substances for analytics (organic substances) have to be soluble in a solvent.

HPLC-equipment Description
UV/VIS Specific detection of substances with known UV/VIS absorption bands
DAD (diode-array-detector) Unspecific detection of the complete UV/VIS spectral width at each time of the chromatogram
ELSD (Evaporative light scattering detector) Detection of substances based on light scattering at particles

NMR-equipment
Description
9,4 Tesla magnet
1H frequency 400MHz
5 mm probe
Automatic tune between 1H and 19F and between 31P and 109Ag, field gradient up to 140 G/cm
2-channel spectrometer
Measurement of 1D as well as 2D COSY-, HMQC-, HMBC-, NOESY-, ROESY-, TOCSY- and DOSY-spectra
