Instrumentation

Trace organic compounds in liquid and solid samples – screening, quantification, sampling and sample preparation

GC-APCI- / LC-QTOF-MS (Agilent 6550 iFunnel)

High-resolution time-of-flight mass spectrometer for screening and compound identification with atmospheric pressure chemical ionization for GC and electrospray ionization (ESI) for LC coupling and online-preconcentration.

LC-MS-MS (Agilent 6490)

Triple quadrupole mass spectrometer for sensitive target analysis of trace organic compounds like pesticides, pharmaceuticals, household and industrial chemicals.

LC-diode array detection (LC-DAD 1290 Infinity, Agilent)

Automated solid-phase-extraction (Gilson GX-271 ASPEC Large Volume)

Sample preconcentration on solid-phase materials.

Volatile trace organic compounds, e.g. disinfection byproducts in air

GC-MS with Membrane-inlet-MS and Cold Trap

(Trace GC Ultra with DSQ II MS, Thermo Fisher Scientific)

Direct introduction of volatile analytes into MS from aqueous samples by membrane partitioning (MIMS) and cold trap with liquid nitrogen.

Electrochemistry equipment

Potentiostat (EZ Stat Pro, Metrohm)

Voltammetry (VA Computrace 797, Metrohm)

GC-FAIMS (Lonestar, Owlstone)

Analysis of volatile disinfection byproducts and other organic analytes by field asymmetric ion mobility spectrometry (FAIMS).

Gas Detector Array (GDA2.5, Airsense Analytics)

Onsite detection and identification of volatile analytes in air and gas samples by an array of detector techniques (ion mobility IMS, photoionization PID, electrochemistry EC, semiconductor sensors MOS).
