Welch Boltimate core-shell HPLC column particle size is 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.
Bonding Phase Introduction
Boltimate C18: Excellent peak shape and resolution for acids, bases, and neutrals. Exceptional resolution and lifetime.
Boltimate LP-C18: Excellent peak shape and resolution at low pH. pH range: 1.0-8.5
Boltimate EXT-C18: The exist of hybrid organic/inorganic layer extend pH range of silica. pH range: 1.5-12. Can use at 100% water phase.
Boltimate C8: Less retentive than C18, suitable for all kinds of polar compounds; excellent peak shape and resolution for acids, bases, and neutrals.
Boltimate Phenyl: Phenyl propyl column, with spatial structure selectivity. It has better separation effect on achiral isomers. Suitable for the separation of polar and aromatic mixtures; Excellent peak shape for alkaline substance. Can use at 100% water phase.
Boltimate Phenyl-Hexyl: Alternative selectivity for phenyl groups. Can use at 100% water phase.
Boltimate EXT-PFP: An alternative selectivity for halogenated compounds and polar analytes. Wide pH range. Has good separation when analysis strong polar compounds and isomers.
Boltimate HILIC: With its unbonded silica, Boltimate HILIC retains and separates polar analytes.
