There’s no question the latest version of the NIST Mass Spectral Library is an invaluable resource. But what happens when Chemistry PhDs, pharmaceutical professionals and mass spectrometrists have a question about the results? Or, if they need to know how the program interfaces to other software? When issues like these arise, that’s when customer support comes in handy!
Expert Advice and Assistance
Meet David Sparkman, the man with the answers when it comes to NIST 14! With more than 100 literature citations for presentations, posters or peer-reviewed papers, Sparkman specializes in solving analytical puzzles of hidden organic structures in complex matrices. In addition to teaching courses in the interpretation of mass-spectral data on the graduate level at University of the Pacific, the adjunct professor of chemistry has written four books on mass spectrometry and gas chromatography mass spectrometry. His entire professional career has involved analytical chemistry in one form or another—from gas chromatography and the interfacing of gas chromatography to infrared spectrophotometer and mass spectrometers to DART (direct analysis in real time) mass spectrometry. In other words, Sparkman is ready, willing and able to share his insights via the NIST library’s customer support.
Errors Stink—but are corrected
Even though the NIST Library database has been thoroughly evaluated, it’s impossible to catch all of the things that can happen—especially when mass spectra of two compounds can be similar. This is one way David can help. If, for example, the initial submitter confuses the spectrum with the structure, there’s a chance it can be incorrectly entered into the database. This happened with two structures associated with the musty odor of cheese. These two compounds were submitted in the NIST database by someone who published a peer reviewed paper in a reputable journal in 1995. The paper stated Spectrum A belonged with Structure A and Spectrum B belonged with Structure B. But recently, a database user challenged these findings because he knew someone else had published the spectra of those two compounds. It appeared the original author had confused spectra A and B (that Spectrum A belonged with Structure B and Spectrum B belonged with Structure A) and to prove this, the new user synthesized one of the compounds and successfully got a spectrum that proved a switch had been recorded. As a result, the correction will appear in the next issue of the database.
According to Sparkman, examples like this, and the fact that new spectra are being added as mass spectrometry’s use rapidly expands in science and industry, are important reasons to be using the most up-to-date version of the library.
