The Mass Spectrometry Core Laboratory has 1,000 square feet of laboratory space dedicated to providing analytical capabilities to support the Michigan Tech mission. The laboratory provides advanced research instrumentation for chromatographic separation, mass spectrometric, and spectroscopic analysis of molecular and elemental species, important in both basic and applied research applications. Sample preparation and analysis by gas/liquid chromatography, mass spectrometry, and ultraviolet-visible spectroscopy.
Software
MFAssignR
This is a custom R package designed for multi-element molecular formula (MF) assignment of ultrahigh resolution mass spectrometry measurements. The MF assignment algorithm was adapted from the low mass moiety CHOFIT assignment algorithm. In total there are 2 versions of MFAssign, including MFAssign() and MFAssignCHO(), where MFAssign() includes external nested loops to assign additional heteroatoms, while MFAssignCHO() does not. A number of tools for internal mass recalibration, MF assignment, signal-to-noise evaluation, and unambiguous MF assignments are provided. This package contains MFAssign(), MFAssign_RMD(), MFAssignCHO(), MFAssignCHO_RMD(), SNplot(), HistNoise(), KMDNoise(), RecalList(), Recal(), Recal_2(), RecalX(), Recal_2X(), and IsoFiltR().
