Blossmate PSV C18, Cartridge:  5µm, 120Å,  4.6×10mm, 2pcs

Welch guard cartridges use the same packing materials as the analytical column to ensure the best analysis results. When HPLC column ID<4.0mm, it is recommended to use a 2.1×10mm cartridge, while when column ID≥4.0mm, a 4.6×10mm cartridge is recommended. 2.1×10mm cartridge holder: 00808-01107, 4.6×10mm cartridge holder: 00808-01101 or 00808-01108(direct connect).

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

Blossmate PSV C18 is a newly developed HPLC column which can be compatible with high proportion of aqueous phase. Taking super high purity spherical silica as matrix, it bonded high-density alkyl functional groups. Its packing materials have high selectivity and strong retention ability for hydrophilic and polar compounds which are often difficult to be retained and separated in normal C18 columns. Blossmate PSV C18 is fully end-capped, which greatly enhances the packing materials’ stability. Even under neutral pHcondition, it keeps stable baseline and high sensitivity, making it particularly suitable for high efficiency separation columns with LC-MS. Now, it is widely used in the separation and analysis of oligosaccharides, amino acids, small peptides, nucleotides, organic acids and other active components.
