Coresil Core-Shell HPLC Column

Labo4u Coresil core-shell HPLC column particle has a size of 2.7 µm, and consists of 1.7 µm solid core and 0.5 µm porous layer(porous shell). This type of column can provide sub-2 µm efficiencies (~200,000 p/m) and high resolution at much lower back pressure. Coresil core-shell column can be used on both HPLC and UHPLC systems, with straight-forward method optimization process.

  • Sub-2 µm efficiencies (~200,000 p/m) and ultra-high resolution at much lower back pressure
  • Ultra-fast separation
  • Compatible with both HPLC and UHPLC systems
  • Narrow particle distribution
  • A standard 2 µm inlet frit prevents plugging by dirty samples, suitable for complex sample analysis
  • A variety of bonding phases provide choices of different selectivities, while always maintaining excellent peak shape and lot-to-lot reproducibility
  • Maximum pressure: 600 bar

Theoretical Plate Number and Column Pressure

  • Coresil C18 column efficiency is almost the same as that of 1.8 µm porous C18 column, and two times that of 3 µm porous C18 column.
  • Even with 2X faster flow rate, the pressure of Coresil is still lower than that of 1.8 µm porous C18 column of the same dimensions under the same analysis conditions, without sacrificing efficiency at the same time.
