Wiley KnowItAll Mass Spec Training - Part 2: ProcessIt for Manual Processing of EI GC-MS Data

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 second part we will look at:

Detailed Handouts including tables of content are available in the LabRulezGCMS library.

• Open ProcessIt In Spectral Processing Group of Programs And Test Files Such as V50.cdf Found in MS Expert Folder
• Horizontal Zoom or Box Zoom Mode to Expand Chromatogram
• After Zooming, MUST Right Click and Get Select Option to Click on Chromatogram Window to Get a Spectrum or Get Pointer from Menu Bar
• Select Spectrum of Interest by Left Click on Peak of Interest In Chromatogram Window, Sent to Bottom Display
• Center Window Can Be Minimized by Hovering Over the Line On the Edge of Its Box to the Mouse Pointer Changes
• Select Either Show Unit Masses for Nominal Mass Data or Show Accurate Masses for Accurate Mass Analyses
• Manually Obtaining Average Spectra Over a Range
• Manually Subtracting Background from a Range of Spectra
• Changing Background and Foreground Ranges
• Removing Background and Foreground Ranges
• More Than One File Can Be Open at a Time
