Description	Gradient elution improve peak capacity with respect to isocratic conditions and should be preferably used in 2D LC x LC in both dimensions. Gradient conditions spanning over a broad range are used with generic %22full in fraction%22 (FIF) gradients. %22Segment in fraction%22 (SIF) gradients cover a limited gradient range. Optimization of the gradient profiles is important tool for achieving high 2D peak capacity and savings of the separation time. The transferred fraction volumes may significantly affect the bandwidths, especially at high elution strength of the fraction solvent, which may cause even band distortion or splitting in combined normal-phase (HILIC)-RP systems, but also in some 2D RP-RP systems. In the present work, the effects of the fast gradient profile, of the sample volume and solvent on the elution time and bandwidths were investigated on a short column packed with fused-core porous-shell particles, providing narrow bandwidths and fast separations at moderate operating pressure.
