MALDI Matrix Information
Note that we are in the process of updating and expanding the matrix-assisted laser desorption ionization (MALDI)
matrix information available at the following wiki site:
The wiki provides both chemical and spectral information about commonly used MALDI matrices.

The information on the static web-pages linked below was collated by Theresa Huh in the late 1990's; spectral data is contained in GRAMS .SPC format files. Note that more extensive data is provided in the wiki listed above; spectral data is saved in JCAMP format and displayed using the open-source JSpecView application.
