Data Analysis
Intelligent Component Recognition
- Employ the Intelligent Component Recognition workflow (IXCR 2.0) to streamline identification of "known unknowns" in mixtures through spectral searching.
- Characterize chromatographic components by searching their associated MSn spectra against public and/or user-created spectral databases (*.nd9 or *.cfd formats)
- Screen GC/MS data using MS1 spectra, and LC/MS data using MS2 spectra (recommended)
- Conveniently review the top result for each component in tabulated view
- Evaluate hit quality via mass difference (Da, mDa, or ppm units), and numeric MS Match values
- Right-click to expand the structure candidate list for each component, with the ability to customize the total number of hits displayed
- Easily evaluate top structure hits using mirrored plot comparisons of experimental and database MS spectra
Intelligent Component Extraction—IntelliXtract
- Manually adjust the mass accuracy (Da) specified for assignment
- Differentiate between isobaric ions or isomers that partially co-elute
Targeted Component Recognition—IntelliTarget
- Track any formulae/structures that are not found by IntelliTarget (which detects compounds that are specified prior to spectral deconvolution) by choosing to include them in tabulated view.
- Compounds not assigned to peaks are labeled "Not Found" in the MS Match column
Metabolite Identification—User-Defined Reactions
- Identify a greater number of metabolites and degradants through addition of User-Defined Reactions. Simply specify a generic reaction mechanism, for example conversion of C=O → C-OH, and generate any relevant metabolites formed by this process
Peak Tracking
- Track peaks more efficiently by transferring unique entity names from the Table of Peaks to the Table of Components
Data Display
- Visualize multiple MSn spectra simultaneously through improved MS Tree control
- All spectra, or only selected spectra, can be displayed

Known Structure Identification Add-On
Simplify unknown compound identification/dereplication by determining whether the compounds' experimental 13C resonances match the predicted signals of known structures. Uses ACD/Labs leading, proprietary NMR prediction neural network algorithms.
- Uses a database of ~98 million known structures collected from open chemistry databases (e.g. PubChem) with predicted 13C NMR spectra
- Rapidly search using individual 13C, HSQC, or HMBC NMR spectra
- Conveniently view results in terms of the average chemical shift deviation between experimental and predicted spectra and their structure and database ID
Search results for the 13C NMR spectrum of Retrorsine. The query spectrum is green and offset vertically from the hit spectrum, which is shown in red. The list of hits is shown in the window below the spectra.
Data Analysis
Enhanced 1D NMR Mixture Analysis Tools:
- Conveniently compare spectra with automatic peak height and chemical shift offset scaling
- Automatically rank hits within a spectral search region
- Easily control the offset between a query spectrum and its respective hits
The new "Optimize Hit" feature can be seen in the spectra comparison menu on the left-hand side of the figure. The query spectrum is shown in green, the original hit is shown in red, and the blue line is the optimized hit curve.
Multiple tools and improvements have been added to version 2018.1. The highlights include:
- Improved peak picking and multiplet assignment accuracy of fluorinated molecules
- Automatically assign Homonuclear coupling partners, in some cases potentially eliminating the need for a COSY Spectrum
