*1.6 mm of core and 0.5 mm of superficially porous silica layer

*Same efficiency and high throughput as a Sub 2mm particle

*Same pressure as a 3 mm particle (less than a half then a sub 2mm particle)

*Same chemistry as Sunniest technology (reference  figure 1)

*Good peak  shape for all compounds such as basic, acidic  and

chelating  compounds

*High stability ( pH range for SunShell C18, 1.5  to 10)

* Low breeding
