The UNISON UK-C18 columns prevent phase collapse and provide stable retention even for nucleic bases under hydrophobic conditions.

• High efficiency columns
• Low back pressure
• LC-MS compatible
• High reproducibilty
• Unique endcapping technology
• Outstanding steric selectivity,hydrogen bonding capacity, hydrophobicity
• Ultra high flow rates with 3 µm particles that can handle higher pressure

Conventional ODS silica phases are designed for the separation of polar compounds. UK-C18 gave excellent peak shapes and rapid sepration compared to 3 µm, 5 µm, 150 mm columns. High durability with both acidic and alkali solutions.

The Unsion series packing material is manufactured in a propertiary manner different from conventional methods, achieving not only high-efficiency packing material but also level of batch-to-batch reproducibilty.
