Sunpure-HS Series Chromatographic Packing Material

Sunpure-HS series is a premium silica gel chromatographic packing material featuring advanced sphere packing technique with excellent control over particle size and pore size distribution. It offers higher resolution, better stability under high pH, and higher mechanical strength, making it particularly suitable for the purification of polypeptide products including GLP-1 and its analogs.

Key Features and Advantages

Uniform particle size distribution
Advanced bonding technology support
Lower column pressure with high column efficiency
High-purity silica matrix
Low metal surface density
Excellent mechanical strength

Low Metal Residue

The minimized metal microstructure on the silica gel surface prevents changes in solute shape and retention characteristics, particularly important for sensitive compounds like 2,3-dimethylpyridine.

Reduced metal-catalyzed degradation

Improved peak symmetry

Enhanced compound recovery

More reproducible results

Highly De-activated Surface

When pH > 7, the deactivated surface minimizes peak shape deterioration for basic compounds like amitriptyline, with retention characteristics serving as indicators of chromatographic performance.
