Ultisil UHPLC Polar RP, Cartridge: 1.8μm, 120Å, 4.0×5mm, 2pcs

Welch UHPLC guard cartridges use the same packing materials as does UHPLC column to ensure the best analysis results. When 2.0 <ID ≤3.0mm, it is recommended to use 2.1×5.0mm cartridge, while when 3.0 <ID ≤8.0mm, 4.0×5.0mm cartridge is recommended. UHPLC cartridge holder: 00808-01109.

Welch UHPLC guard cartridges for analytical columns are sold in packs, each pack containing 2 pieces (1 unit = 1 pack = 2 pcs).

Ultisil UHPLC Polar RP column is packed with 1.8 µm high-purity silica and can withstand pressures up to 15,000 psi. Being a reversed-phase column with selectivity distinct from conventional C18, it incorporates embedded polar groups, allowing the alkyl phase to remain solvated even in highly aqueous mobile phases (up to 100% water) without hydrophobic collapse. It offers enhanced retention and selectivity for polar compounds.
