Welch Materials Boltimate Columns

Welch Boltimate core-shell HPLC columns have a particle size of 2.7 μm, which consists of 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, and method optimization is also very easy.

Features

• Provide sub-2 μm efficiencies (~200000 p/m) and ultra-high resolution at much lower back pressure
• Ultra fast separation
• Compatible with both HPLC and UHPLC system
• Narrow particle size distribution
• A standard 2 μm inlet firt is used to resist plugging with dirty samples, suitable for complex sample
• A variety of bonding phases provide different selectivities, excellent peak shape and lot-to-lot reproducibility
• Maximum pressure: 600 bar

With the solid core and thin porous layer, the diffusion distance of sample molecular deceased, which means fast mobile phase flow rate can be used to increase the analytical speed. Compared with traditional porous HPLC columns, Boltimate core-shell column has the narrower particle size distribution, which provides higher column efficiency, higher resolution and lower back pressure.
