Topsil HPLC Column, low cost alternativ for different selectivities

Topsil series HPLC column is a next-generation column by Welch, besides Ultisil, Xtimate and Welchrom.

This series uses different silica and provides different selectivity.

Features:

• High purity silica (99.99%) with 150 Å pore size and 250 m2/g surface area
• 12% carbon loading for C18 phase
• Because of large pore and moderate carbon loading, Topsil® C18 phase can also be used as AQ-C18 without phase collapse
• Endcapped for excellent peak shape and lifetime
• Lower back pressure than Ultisil, almost the same column efficiency as Ultisil
• Good for small molecules and peptides
• Topsil phases including:
• Topsil C18, Topsil C8, Topsil Phenyl-Hexyl, Topsil Silica, Topsil NH2 and Topsil CN
