Equipment

Our group is equipped with advanced analytical instrumentation for trace analysis of (environmental) organic minorcomponents within a wide range of volatility and polarity.

For on-line trace analysis of VOCs at the ppbv level , we have a PTR-QiTOF (PTR-MS) and a SIFT-MS (Selected Ion Flow Tube).

Further on, we are specialized in both gas and liquid chromatography coupled to mass spectrometry for sensitive and selective detection, such as:

thermal Desorption GC-MS instrumentation
high resolution mass spectrometry hyphenated to both GC and HPLC (HR-MS)
flame ionization detection (FID-GC)
UV-VIS PDA-detection (UV-VIS-HPLC)

For sampling and sample preparation of air, water and solid matrices:

whole air sampling (e.g. with Nalophane bags)
passive and active sorptive sampling (e.g. by use of Tenax-containing sorption tubes, PDMS-based SPME and SPDE devices,…)

extraction and clean-up instrumentation like ultrasonic and accelerated solvent extraction (ASE) and solid-phase extraction (SPE)
