ECoreshell Series HPLC Columns were developed by ELITEHPLC with decades of expertise. Under the same chromatographic conditions, core-shell chromatography columns can achieve column efficiency comparable to most sub-2μm porous particle chromatography columns, with column pressure only half that of sub-2μm porous particle chromatography columns. Due to the presence of the solid core, the mass transfer path for sample molecules is shortened, significantly improving analysis speed. It enables achieving ultra-high column efficiency and faster separation on conventional HPLC systems.
Octadecylsilane-bonded solid particles chromatographic column, achieving higher column efficiency and faster analysis speed while maintaining lower column backpressure, compatible with ultra-high performance/analytical systems

| Stationary Phase | Particle Size (μm) | Specific Surface Area (m2/g) | Pore Size (Å) | Carbon Content (C%) | End-capping |
|---|---|---|---|---|---|
| ECoreshell SOS C18 | 2.7 | 150 | 90 | 9 | Y |




The ECoreshell SOS C18 chromatography column is bonded with C18 functional groups. Starting from the synthesis process of the core-shell structure, it is completely different from the Supersil Coreshell series, creating a brand-new core-shell chromatography column series.
