In comparison between fully porous. mm and core shell. mm (SunShell), SunShell shows lower values for A term, B term and C term of Van Deemter equation. The core shell structure leads higher performance to compare with the fully porous structure. Furthermore back pressure of SunShell C8 is less than a half to compare with sub- mm C8s.

Comparison of Particle ze Distribution Wide particle distribution (Conventional silica gel D 9 /D =.) Flow of mobile phase Narrow 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. Consequently B term in Van Deemter Equation reduces in the core shell silica column. B term Totally porous silica Core 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 C term in Van Deemter Equation reduces. In other words, HETP (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.

Sodium borate is used as a alkaline standard solution for ph meter, so that its buffer capacity is high. Elevated temperature of ºC makes column life be one third. The other company shows stability test at ambient (room temperature). If room temperature is ºC, column life at room temperature ( ºC) is sixteen times longer than that at ºC. SunShell C8 is enough stable even if it is used under ph condition. Regarding stability under basic ph condition, there is little C8 column like SunShell C8 except for hybrid type C8. It is considered that our end-capping technique leads high stability. SunShell C8 can be used at the ph range from. to.
