Accurate mass spectrometry

The Accurate Mass Spectrometry Lab is equipped with an Orbitrap GC-MS mass spectrometer. The use of the Exactive GC (Orbitrap technology), allows to perform highly sensitive analyzes on targeted and untargeted compounds, combining the robustness of a reliable quantitative analysis tool with state-of-the-art processing software. The resolving power (up to 50.000 (FWHM) m / z 272), the mass precision lower than ppm and the detection limit <4fg TCDD allow the study of ultra-trace analysis of extremely sensitive samples such as those of areas remoyou. The specificity of the analyzes is also given by the possibility of using both the electronic and chemical ionization source (EI / CI).

The experience of the working group allows to put specific analytical methods for different classes of pollutants. In fact, the work carried out in recent years allows to carry out preliminary screening of Unknwon compounds on different matrices and to pass in a subsequent phase to the quantitative analysis of the same. This is also possible through the development of sampling and purification methods upstream of the instrumental determination system on classes that go beyond the routine of regulated pollutants (eg Emerging Pollutants).
