Unison UK-C18 is a high-resolution, fast 3μm ODS column that inherits the performance of Cadenza UK-C18. Compared to traditional 5μm particle columns, it offers superior speed and high separation performance.
It demonstrates stable retention characteristics for the separation of highly polar substances using a 100% aqueous mobile phase and also excels in the elution characteristics of low-polarity compounds. Unison UK-C18, which accommodates a wide range of polarities, is the first choice for versatility among IMTAKT ODS columns.
The industry-leading low-pressure 5μm ODS column, Unison US-C18, has the same surface structure as the UK-C18 (3μm) and is a high-performance 5μm column compatible with pharmacopoeia methods.
Low Carryover
Unison UK-C18 demonstrates excellent low carryover performance in LC-MS analysis of pharmaceuticals. This is believed to be due to the development of a different method from conventional packing material synthesis and a novel polymeric end-capping technique.
