In comparison between fully porous. μm and core shell. μm (SunShell), SunShell shows lower values for A term, B term and term of Van Deemter equation. The core shell structure leads higher performance to compare with the fully porous structure.
Why does a. μm core shell particle show the same performance as a sub μm particle? All terms in Van Deemter Equation reduce.

Flow of mobile phase arrow particle distribution (core shell silica D 9 /D =.) Packing state of core shell and fully porous silica The size distribution of a core shell (SunShell) particle is much narrower than that of a conventional totally porous particle, so that the space among particles in the column reduces and efficiency increases by reducing Eddy Diffusion (multi-path diffusion) as the A term in Van Deemter Equation. Diffusion of a solute is blocked by the existence of a core, so that a solute diffuses less in a core shell silica column than in a totally porous silica column. onsequently B term in Van Deemter Equation reduces in the core shell silica column. B term Totally porous silica ore shell silica A solute diffuses in a pore as well as outside of particles. A core without pores blocks diffusion of a solute.

This means that the term in Van Deemter Equation reduces. In other words, ETP (theoretical plate) is kept even if flow rate increases. A. mm core shell particle shows as same column efficiency as a totally porous sub- mm particle. The right figure shows that a diffusion width of a sample in a. mm core shell particle and a mm totally porous particle. Both diffusion widths are almost same. The. mm core shell particle is superficially porous, so that the diffusion width becomes narrower than particle size. Same diffusion means same efficiency.

A tubing with a large inner diameter has a large dead volume, so that it makes the peak width be wide. As a result, theoretical plate decreases. I recommend to use the tubing with. mm or less than. mm inner diameter for core shell columns. The response time of a detector is important. Regarding uracil, the real peak width is less than.8 sec. When the peak width is less than sec,. sec of response time is needed. Furthermore, the sampling rate of an integrator should be set to be. sec.

Indeed regarding high-throughput separation under minute gradient elution, SunShell 8-. μm with. μm thickness porous layer showed shaper peaks than. μm with. μm thickness porous layer. owever, under long gradient elution at 8degree elsius, a reversed phenomenon is observed. The difference of a peak width is bigger than the value due to the difference of a particle size. As a result, the thickness of the porous layer has nothing with the peak width of a protein under such a condition. Regarding retention time, the wider the surface area, the longer the retention time. In other words, the partition interaction on a. μm porous layer material worked for longer time, so that BSA and ovalbumin was separated much better on. μm porous layer material than. μm porous layer material.
