The Automated Mass Spectral Deconvolution and Identification System (AMDIS) is a computer program that extracts spectra for individual components in a GC/MS data file and identifies target compounds by matching these spectra against a reference library. It was developed at NIST with support from the United States Department of Defense and is freely available.
