Correlation between the Charge of Polymer Particles in Solution and in the Gas Phase Investigated by Zeta-Potential Measurements and Electrospray Ionization Mass Spectrometry.
The relationship between the effective
charge of polymer nanoparticles
(PNP) in solution and the charge states of ionized particles produced
in the gas phase by electrospray ionization was investigated. Charge
detection mass spectrometry was used to measure both the mass and
charge of individual electrosprayed ions. The effective charges extracted
from the measured zeta-potential of PNPs in solution are partially
correlated with the average values of charge of PNPs in the gas phase.
The correlation between the magnitude of charging of PNPs ions produced
in the gas phase with the PNPs surface charge in solution demonstrates
that the mass spectrometry-based analysis described in this work is
an alternative and promising way for a fast and systematic characterization
of charges on colloidal particles
