Chemical characterization of microparticles by laser ablation in an ion trap mass spectrometer
Laser Ablation Mechanisms and Applications
We are developing a new technique for the chemical characterization of microparticles based upon the use of electrodynamic traps. The electrodynamic trap has achieved widespread use in the mass spectrometry community in the form of the ion trap mass spectrometer or quadrupole ion trap (1). Small macroscopic particles (microparticles) can be confined or levitated within the electrode structure of a three-dimensional quadrupole electrodynamic trap in the same way as fundamental charges ordoi:10.1007/bfb0048391 fatcat:ljhyb3o6ana5jcx4323kie4k6y
