Services

The facility is equipped to handle a variety of sample types including inorganic, organic, biological and technical polymer samples. If you have questions about your particular analysis needs, techniques available, or pricing information, please contact our staff.

At the present time, our facility is equipped with the following instrumentation:

Thermo Scientific LTQ-FT

The Thermo Scientific LTQ-FT™ is a hybrid mass spectrometer, combining linear Ion Trap and a Fourier Transform Ion Cyclotron Resonance technologies into a single instrument with unprecedented analytical power and versatility. While the FT-ICR is providing high mass accuracy and high resolution mass spectra, the linear ion trap can simultaneously provide multiple collision-induced dissociations for structural identification. Extremely sensitive while possessing a mass accuracy of less than 1 ppm, mass resolution exceeding 100K, and MSⁿ capabilities. Generally used for accurate mass, and LC-MS for general biological and chemical samples.

Bruker ultrafleXtreme MALDI-TOF-MS

This instrument can be used for the rapid analysis of a large variety of samples including peptides, proteins, synthetic polymers, oligonucleotides, and higher molecular weight organic materials. In external calibration mode, the mass accuracy on this instrument is typically about 0.5%. Mass accuracy can be improved to 0.1-0.2% with internal calibration.

Agilent 5977A/7890B GC/MS System with Agilent 7697A Headspace Sampler

This instrument is available for "self-run" samples in an open access environment. Self-run is only for groups within the University of Cincinnati and requires individuals be trained and approved by the mass spec facility personnel. Analysis of outside UC samples are performed by the facility personnel. This instrument is equipped with a standard Electron Ionization source (EI). Samples can be introduced manually, using the Auto Liquid Sampler (ALS), or the Headspace Sampler. The instrument has NIST GC Compound Library search capabilities to facilitate the identification of unknowns.
