AMDIS
The Automatic Mass Spectral Deconvolution and Identification System (AMDIS) allows you to automatically
find any of a set of target compounds in a gas chromatography/mass spectral (GC/MS) data file. The program
first deconvolutes the GC/MS data file to find all of the separate components. Each of these components is then
compared against a library of target compounds. The match factor between the target spectrum and the
deconvoluted component spectrum is then reported, if it is above a user set value.
AMDIS uses a library of mass spectra with or without retention indices to identify compounds in the data file.
The program can be configured to build a retention index calibration file, to use the retention index data along
with the mass spectral data or to work without reference to any retention index data. In addition, AMDIS can be
used to build a user defined library, either from GC/MS data files, or from the data in the NIST Mass Spectral
Database.
The program will optionally track the results of routine performance mixture runs (such as the Grob test
mixture). Data is retained from previous runs so that changes in the performance of the system can be
monitored.
AMDIS also provides compound class identification, a batch processing capability and a convenient link to the
NIST Mass Spectral Database.
