A MATHEMATICAL MODEL FOR MAGNESIUM CHLORIDE-FATTY ACID ADDUCTS IN ELECTROSPRAY IONIZATION MASS SPECTROMETRY

Abstract

The formation of adducts among analyte species is a well known phenomenon in electrospray ionization mass spectrometry (ESI-MS). The presence of salts usually promotes the formation of adducts by electrostatic and van de waalse bonds among various ions present in solution. In this study, the authors describe a simple mathematical model to explain the patterns for mass distribution and peak intensity for adducts formed by magnesium chloride and various fatty acid anions
