An advanced system for size-dependent cytotoxicity analysis of silica

Separation of particles is conducted based on their size (hydrodynamic radius) using differences in diffusion coefficients. The particles are accumulated at different heights in the AF4 channel. Subsequently, they are eluted from the AF4 channel by horizontal detection flow and constituent elements are monitored by ICP mass spectrometer.
