Preparative & Semi-Preparative HPLC Columns for High-Throughput Purification

Orochem Technologies offers a complete range of prep HPLC columns for preparative and semi-preparative chromatography. Designed for high sample loading, superior separation efficiency, and reproducibility, our columns are available in reversed-phase, normal phase, and chiral formats. Particle sizes range from 5–50 µm and pore sizes from 80–300 Å, with multiple dimensions to suit your purification needs.

Reliasil Preparative HPLC Columns

Engineered for high efficiency and broad application, Reliasil prep HPLC columns are manufactured using a proprietary silica gel process that ensures:

Narrow Gaussian particle size distribution
Uniform pore size for consistent separations
Excellent resistance to high pH conditions

Phases: Silica, C1, C4, C8, C18, C30, NH2, CN, Phenyl, SCX, SAX, Diol, Polyamine, PFP
pH Range: 2-8.5,

Monitor Preparative HPLC Columns

The Monitor phase delivers exceptional stability, reproducibility, and minimal secondary interactions — making it ideal for challenging pharmaceutical and peptide separations. Its base-deactivated design ensures sharp peak shapes and robust performance under demanding reversed-phase prep conditions.
