Chrompure Alumina N SPE Column Description

Acidic pH: ~7.5
Particle Size: 100-200 Mesh
Particle phase: irregular

Alumina N SPE Column Features

• Extremely polar sorbent which is similar to silica, more stable under high pH conditions than unbonded silica
• An electrically neutral surface that is retentive for electron-rich compounds like aromatic species and aliphatic amines, and compounds with electronegative groups like oxygen, phosphorus and sulfur atoms
• Extract both nonpolar and polar compounds from aqueous and nonaqueous matrics respectively

Application

• Extract polar compounds from non-polar matrix
• Remove polar hydrocarbons, organic acids, and phenols in extracts
• Separate compounds with very similar structures (isomers)
• Extract Sudan red and malachite green
