System Requirements: This MS search program is a 32-bit Unicode application and thus requires Windows®NT 4.0, 2000, XP, Vista, or Windows®7, 8, 8.1.
To install, run the program Setup.exe and then follow instructions.
Total installed size is approximately 1.5 GB.
Note: AMDIS, MS Interpreter, and Lib2NIST are not compatible with Windows NT 4.0.
Installation includes MS library, Search Program v2.2g, MS Interpreter v2.0, and AMDIS v2.72.
An Automated MS Deconvolution and Identification System (AMDIS).
AMDIS Extracts the spectrum of each component in a mixture analyzed by GC/MS and identifies target compounds. With the support of the Defense Special Weapons Agency (DOD), it was developed at the National Institute of Standards and Technology (NIST) for the critical task of verifying a major international treaty, the Chemical Weapons Convention. After two years of development and extensive testing it has been made available to the general analytical chemistry community.
