    This position centers around quality assurance for mass spectral reference libraries. The incumbent will review mass spectra for the presence of expected peaks including proper mass and relative ion intensity, will identify any unexplained peaks, and will perform laboratory and/or literature research to explain the molecular origin of unidentified peaks as required. Furthermore, the incumbent will review compound descriptive information for each library entry including, but limited to, compound name, InChI code, chemical formula, molecular mass, compound chemical structure, and the like. On the order of 10,000 spectra will be reviewed per year. Laboratory measurements by gas chromatography-mass spectrometry and/or liquid chromatography mass spectrometry to obtain mass spectra for the mass spectral library, as well as to explain any unindentified peaks in mass spectra, to be performed on an as-needed basis.
