Application
MALDI-TOF質量分析法におけるマトリックス
Matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometry is a standard soft ionization technique in mass spectrometry. Nicotinic acid is often used as a matrix for MALDI-TOF mass spectrometry, for peptide/protein analysis in particular. Incidentally, IUPAC defined standard terms relating to mass spectrometry in 2013 (free access).
