deconvolution run where the software has identified an unknown peak by finding it in an
unknown library.
The unknown peaks are compared to the unknown library which is specified in the
Deconvolution Parameters in the Target Library Editor. The possible matches are sorted on
the Match Factor. In the image below Unknown 12 has three possible matches. The correct
match is Isopropyl Alcohol with a match factor 98.
In the
Deconvolution Parameters
tab of the Target Library Editor the number of
unknown peaks to be displayed can be specified. This is to maintain the speed of analyzing
samples on the instrument. If a complex sample is analyzed and it has a larger number of
unknown compounds the processing can take a long time to complete. By limiting the
number of unknown peaks that are allowed to the 10 largest peaks then the processing on
the instrument can still be kept reasonable.
If a large number of unknowns are expected and the intention is to obtain good search
results for as many of the unknown compounds as possible then this setting can be
increased to allow the software to show all of the unknown peaks.
