James Little: Wiley KnowItAll Mass Spec Training - Part 11. Making a User Library Using NIST MS Interpreter and PubChem
Wiley released a KnowItAll version with many new powerful electron ionization gas chromatography-mass spectrometry (EI GC-MS) capabilities. I have developed FREE training videos and associated handouts covering basic and advanced MS topics that will be helpful to the new user.
Also, a Quick Reference Guide. is available.
KnowItAll is a vendor neutral data processing solution for spectral analyses which will be very valuable in unknown identifications.
It processes IR, Raman, MS, NMR, and UV data employing a large number of file formats (>170) and a total of 2.5 million reference spectra.
- ~264K IR
- ~25K Raman
- ~1.25M EI mass spec
- ~894K NMR
- ~30K UV
Highlights:
- Deconvolution/very fast library searching of accurate/nominal mass GC-MS data
- Easy manual processing of nominal and accurate mass GC-MS data
- Fast EI searches of >1.2 million spectra in <0.5 seconds
- Amazing adaptive search for unknown ID by extending usefulness of all libraries
- Transfer structures and spectra between NIST search and KnowItAll
- Easy structure drawing and structure searches
- Conversion of NIST user libraries to Wiley format
- Easy creation of libraries using links to MS interpreter and PubChem
In the eleventh part we will look at:
Detailed Handouts including tables of content are available in the LabRulezGCMS library.
- Skills Needed from Previous Videos and Handouts
- Another Useful Reference on Databases
- File Used for Demonstration
- Process for Creating User Library (Database)
