MilliporeSigma™ Supelco™ Discovery™ HS F5 Supelguard™ Cartridge Kit, 3 μm Particle Size

The Discovery™ HS F5 bonded phase provides reversed-phase separations that are distinctly different from C18 columns. However, compounds will generally elute within the same retention time window, making most C18 methods easily transferable.

Includes 1 cartridge, a stand-alone holder, a piece of tubing, and 2 nuts and ferrules
Pore Size 120 Å
Particle Size 3 μm
Type Guard Cartridge Kit
Phase Reversed Phase and HILIC
Length (Metric) 2 cm
