Willkommen auf den Internetseiten des Massenspektrometrie-Labors am OCI

Sie finden hier alles zu unserer Einrichtung, der Ausstatttung, den Service-Angeboten und viel Wissenswertes zur Massenspektrometrie.

Der Großteil dieser Website ist auf Englisch verfasst. Lediglich im Bereich Lehre (Teaching) sind die Seiten auf Deutsch, da sämtliche Lehrveranstaltungen ohnehin auf Deutsch gehalten werden.

Thermo Fisher Scientific Exploris 240 Orbitrap

In late 2025, Deutsche Forschungsgemeinschaft (DFG) granted the Thermo Fisher Scientific Exploris 240 Orbitrap mass spectrometer (INST 35/1923-1 FUGG). This instrument represents the long-awaited "true" replacement of aged the FT-ICR instrument. The quadrupole-Orbitrap hybrid geometry enables high resolution (R = 240 k at m/z 200), accurate mass (1-3 ppm), and tandem MS of precursor ions up to m/z 2500. It presents the next generation of Thermo's compact Orbitraps succeeding the Q-Exactive series. It is mainly designed for operation in the m/z 50-3000 range but may reach up to m/z 6000.
In addition to the common ionization methods ESI and APCI, we have acquired a LIFDI source from Linden CMS in addition. In this unique combination, LIFDI is attached to the rear of the Exploris, i.e., via the HCD cell. Thus, LIFDI can be operated without swapping ion sources at any time. In contrast to LIFDI with our JEOL AccuTOF, this type of LIFDI arrangement now enables the same high level of resolution and mass accuracy as ESI and APCI on this instrument.

Welcome to the Website of the Mass Spectrometry Laboratory at OCI

You will find all about our facility, the equipment, our MS service offerings, and lots of things to know about mass spectrometry.

Most of this website content is presented in English.
The section on Teaching presents an exception as all teaching is done in German language anyway.
