Routine Service Measurements

  • Acquisition of low-resolution mass spectra of non-volatile, soluble organic compounds, metal-organic/inorganic complexes, natural products and small peptides (up to ca. 2,000 Da) in positive- and/or negative-ion mode to confirm/determine the molecular weight.
  • Acquisition of high-resolution mass spectra of non-volatile, soluble organic compounds, metal-organic/inorganic complexes, natural products and small peptides (up to ca. 2,000 Da) in positive- and/or negative-ion mode to confirm/determine the accurate molecular weight and verify the sum formula.
    • These measurements are performed on the maXis ESI-Qq-TOF – mass accuracy routinely < ±5 ppm.
  • Characterization of volatile compounds by high-resolution EI mass spectra.
    • These measurements are performed on the 7200B GC/Q-TOF - mass accuracy routinely < ±5 ppm.

These routine service measurements are performed by our experienced technical staff. Members of the faculty can deliver such samples along with a completely filled sample form at our delivery point next to the main entrance of the MSC (ground floor, room 1E29). The spectra are usually available on the server (or as e-mail) within 1-3 working days.
