Ultisil UHPLC PFP, 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 PFP is packed with 1.8 µm high-purity silica and can withstand pressures up to 15,000 psi. It is a phenyl column where fluorine atoms replace hydrogen atoms on the reversed-phase stationary phase carbon chain, offering high selectivity for fluorinated and halogenated compounds. With strong geometric and steric shape selectivity, it effectively separates structurally similar compounds that are difficult to resolve with alkyl stationary phases.
