Boltimate core-shell HPLC column is type of superficially porous particle (SPP) column. Its particle size is 2.7 μm with 1.7 μm solid core and 0.5 μm porous layer (porous shell). This kind of column can provide sub-2 µm efficiencies (~200000 p/m) and high resolution at much lower back pressure. Boltimate core-shell column can be used on both HPLC and UHPLC system. Boltimate EXT C18 has a wider pH range of 1.5-12 as compared to the Boltimate C18 column. 


Key Features

  • Provide sub-2 µm efficiencies (~200000 p/m) and ultra-high resolution at much lower back pressure 
  • Compatible with HPLC and UHPLC system 
  • High column efficiency and fast separation 
  • A standard 2 um inlet frit is used to resist plugging with dirty samples, suitable for complex sample
  • Wide pH 1.5-12
  • Maximum pressure: 600 bar

Typical Applications

  • Widely used in pharmaceutical, chemical industry, environment and food safety testing field
