GCxGC-Analyzer – True Deconvolution

GCxGC-Analyzer is a software product to detect and identify all peaks for comprehensive GCxGC/MS Data. The powerful Differential Analysis algorithm lets you detect minor differences between a sample and control based on either Full TIC processing or comparison of all individual fragment ions. Great for Trouble Shooting or Product Control Applications. NIST MS Library search is used to automatically identify all detected components.

GCxGC-Analyzer can also be used for Deconvolution and ID of a single sample.

Software Features:


Import and Graphical Exploration

Import data from all major vendors. Compare the TIC, Mass Spectra and Extracted Ion Currents from sample and control graphically. GCxGC-Analyzer has different views to explore the large amount of data; e.g. 3D Plots, HeatMaps, Selected Ion Maps, TIC and Mass Chromatograms for the second dimension time scale.

Peak Detection

GCxGC-Analyzer detects all significant ions in your data file having true chromatographic peak shapes in just a few seconds. Peak Detection can be performed on the TIC or on all individual fragment ions. Using the “all ion mode”, many more small components will be detected!

Differential Analysis

Run Differential Analysis to find all components that are different between sample and control at a very low level. Use Differential Analysis during Trouble Shooting or Product Control. The Dot or Bubble plot easily lets you explore all ions that are different. All graphs are highly interactive. Quickly get a list of differential components plus their ID’s.


Probably the most difficult step in GC/MS data analysis is Deconvolution. GCxGC-Analyzer uses different levels of deconvolution depending on the complexity of the data. Deconvolution can be based on the TIC or using the powerful “All Ion” Mode, for more complex samples. Results of deconvolution can be viewed for all detected components or using only differential peaks. Deconvoluted spectra are submitted to NIST MS Search to run a full identification.


GCxGC-Analyzer links directly with the NIST MS Search program. Identification can be done based on the full data set or just a single selected peak.
