Pyrolysis GC-orbitrap MS en GC-orbitrap MS


Highly sensitive and accurate mass spectrometry (OrbiTrap MS) connected to a pyrolysis-GC combination for a versatile and dedicated application to characterise and quantify lignin in complex (insoluble) matrices as plant materials including biomass. A second GC unit connected to the OrbiTrap MS widens the number of applications of the system to quantify and identify unknown compounds, in particular fat and fat oxidation products, in complex mixtures.

The OrbiTrap MS is a powerful technique for unambiguous accurate mass determinations to 0.0001 amu (atomic mass unit (Da)) accuracy. The OrbiTrap has internal mass calibration and is equipped with multiple ionization possibilities (EI, VeV, CI) allowing detailed mass spectra for precise identification.
