Abstract
In this paper, we present the nonlinear damping identification method for the fast and comprehensive study of individual microparticles localized in a quadrupole electrodynamic Paul trap. The measurement procedure is discussed in detail. The size, mass and charge of individual silica microspheres from the studied sample are determined simultaneously and non- destructively. Experimental results agree well with the results of independent microscopic examination and density reference values. The further development of the method are outlined.
