HPLC Guard Column Ultracore SuperPhHex, 3 - 4.6 mm, 5 pc/PAK

ACE® UltraCore™ SuperPhenylHexyl™ solid-core (core-shell) particle columns are ideal for demanding MS work offering improved MS signal intensity and maximum MS response. These stainless steel columns combine high efficiency separations with low column back pressure. The Encapsulated Bonding Technology (EBT™) greatly increases the ligand coverage of the silica surface and effectively eliminates the effect of unbonded silanol groups on separations. This higher ligand coverage results in improved inertness, chromatographic performance and stability.

• Excellent peak shape and phases stability with extended pH
• Complementary selectivity to C18 columns
• Highly inert, ultra-low bleed, designed for use with LC/MS compatible buffers
• Available with 2,5 and 5 µm particle sizes and microbore to analytical dimensions
• Maximum recommended pH: 1,5 to 11,0
• Max. pressure: 400 bar for microbore columns, 1000 bar for analytical columns
