massive-cluster impact ionization (MCI)

Massive-cluster impact ionization (MCI) is a method for generating ions by bombarding a liquid matrix sample solution spread on a metallic target plate with multiply charged cluster ions of glycerin accelerated to 10 ~ 20kV. The clusters are proto-nated 20 ~ 300 times, have masses of 107 or greater, and have diameters on the sub-micro level (~0.01µm). The measurement method is the same as FAB. The multiply-charged cluster ions are gen-erated by electrohydrodynamic ionization.
