This document introduces a new product from Orient Electronics. The product has the following features:
The document describes the Agilent Technologies POROSHELL 300SB-C18, a unique microparticulate superficially-porous C18 column packing designed for ultra-fast gradient separations of macromolecules. The material features a special silica support with covalently bonded sterically-protected C18 stationary phase, making it stable at low pH and suitable for aggressive mobile phases.
| Particle Size | 5-um silica particles |
|---|---|
| Shell Thickness | 0.25-1m-thick shell of 300A pores |
| Nitrogen Surface Area | about 4.5 m?/g |
| Maximum Operating Pressure | 400 bar (6000 psi) |
| Max Temp at pH <5 | 70°C |
| Max Temp at pH 5-8 | 40° C |
The maximum operating pressure is 400 bar or 6000 psi.
The column should be avoided below pH 0.9 or above pH 8.0.
It should be stored in a pure organic solvent, preferably an aprotic liquid such as 100% acetonitrile.
