โœฆ Synopsis

Field desorption mass spectrometry (FD-MS) has been evaluated for the analysis of low molecular weight polyethylene by using samples in the molecular weight range 600-2000 u as determined by gel permeation chromatography.

The repeat units and end group's were characterized by FD-MS, but it was demonstrated that accurate molecular weight distribution data cannot be obtained for polyethylene by FD-MS because there is mass discrimination against the higher molecular weight polymers. (

Field desorption mass spectra have been recorded of n-dotriacontane, n-tetracosanoic acid and hexadecyl hexadecanoate as representatives of long straight-chain alcohols, acids and esters respectively. Molecular or quasimolecular ions were formed almost exclusively with fragmentation at a low level.
