VOCal comprises a versatile set of features for quantitative data evaluation and method development same as tools that support compound identification. By that it merges functionalities of the former LAV- and GC-IMS Library Search and contains new visualization and evaluation strategies.
Visualisation and organisation of GC-IMS measurements in *.MEA format
In to the aforementioned functionalities further useful data analysis tools support analysts to compare entire chromatograms with respect to 1, 2- or even 3-dimensional data representations and are powerful tools for determining and evaluating signal patterns. Beyond that they facilitate identifying specific marker compounds or different amount of the same present substances within different samples and enable a comprehensible graphical representation of the result.
The ‘ Reporter’ plug-in is a very useful tool for re/-presentation, combination and analysis of GC-IMS data to quickly visualize entire chromatograms, compare them with or even substract them from each other to visualize differences of volatile composition of a sample within a second. The ‘ Gallery Plot’ cuts out selected compound peaks within chromatograms and allows to compare their intensities in bigger datasets in order to visualize similarities or differences in the fingerprint of samples, show in- or compound decrease over time or rather variations in intensities.
