UNM Mass Spectrometry Instrumentation
Xevo G2 XS Quadrupole Time-of-Flight (QToF) Mass Spectrometer with UPLC and GC sample introduction/separation.
 |
Manufacturer: Waters, Milford, MA
Specfic Features:
- Mass resolution of the QToF (> 40,000 FWHM at m/z 1000) allows for exact mass determinations for novel compounds. The mass accuracy and resolution are well within 5 ppm.
- Mass range of molecules (up to m/z 100,000) enables mass measurements on purified proteins and peptides.
- Tandem MS/MS experiments and multi-reaction monitoring (MRM) capabilities for structural and quantitative analyses for small molecules.
- Sample introduction methods including Gas Chromatography, infusion, and UPLC.
- Auto-samplers aid in temperature sensitive and high throughput analyses.
Acquisition Date: 2019
Uses: Exact mass determinations, protein mass measurement

SHIMADZU MALDI-8020 Benchtop Linear MALDI-TOF Mass Spectrometer
Specific Features:
1. Linear mode (positive ion) MALDI-TOF with a 200 Hz solid-state laser, 355 nm.
2. A single steel target plate can load 48 samples at once for rapid sample analysis.
3. Peptides, proteins, polymers or oligonucleotides - the instrument is capable of delivering the performance required for QC applications.
4. To maximize uptime, the system is equipped with TrueClean - an automated, rapid (<10 min) UV laser-based source cleaning which can be used to clean the extraction electrode in-situ without breaking instrument vacuum.
