The Fused-Core particle consists of a 1.7 micron solid core and a 0.5 micron porous shell yielding a 2.7 micron diameter. One of the benefits of the Fused-Core particle is the small diffusion path (0.5 microns) compared to conventional fully porous particles. The shorter diffusion path minimizes peak broadening. In fact, there have been many reports on the vast improvements in efficiency provided by Fused-Core particles versus conventional particles. These improvements provide sub-2 micron like performance at half of the backpressure allowing Ascentis Express columns to be used in conventional HPLC as well as UHPLC systems.
