Analysis of intact phospholipids by field desorption mass spectrometry

Abstract

The first application of field desorption mass spectrometry to the analysis of intact diacyl glycerophosphorylcholines (lecithins) has led to the detection of prominent molecular ions. This technique enables positive identification of the components of a mixture of phosphatidylcholines, which will provide valuable information on the phospholipid composition of biological fluids.
