Matrix-assisted laser desorption/ionization matrices for negative mode metabolomics.

Stephan R Fagerer et al.

European journal of mass spectrometry (Chichester, England), 19(1), 39-47 (2013-07-12)

Matrix-assisted laser desorption/ionization (MALDI) has been shown to be highly sensitive for analyzing low-mass compounds such as metabolites if the right matrix is used. 9-aminoacridine (9AA) is the most commonly employed matrix for negative mode MALDI-MS in metabolomics. However, matrix
