High quality long-life Amino column for carbohydrate or Hilic separations.

The Unison Family of columns provide a wide range of high quality reverse phase and normal phase columns. The quality of our material provides high efficiency with low backpressure and 100% aqueous stability. Peak shape is also improved with the use of our polymeric end-capping technology. The Unison series of columns are available with C18, C8, Phenyl, Amino and Silica stationary phases to meet a wide range of chromatographic needs.

  • Pure spherical porous silica 3µm particle Aminopropyl phase
  • High efficiency 3µ columns with mono-dispersed packing for low backpressure
  • Normal phase aminopropyl material ideal for analysis of sugars and carbohydrates
  • World class reproducibility
  • HT and UP hardware able to operate in pressures up to 1000 bar
  • High efficiency and available short column dimensions are ideal for high throughput applications
  • Aqueous to non-aqueous Normal Phase separation
  • LC-MS applicable
  • Unique ligand binding strategy provides dramatically longer lifetimes and lower bleed compared to other amino columns

Aqueous durable silica-based aminopropyl columns have been used for a long time as a normal phase column for carbohydrate separation. However, these aminopropyl columns have a fatal flaw: "column bleeding" or the rapid deterioration in retention as a result of ligand desorption under aqueous elution.

Unison UK-Amino offers a different approach from conventional columns: high durability against aqueous eluent. As the above chromatogram demonstrates, conventional columns experience a significant decline in retention when an aqueous mobile phase elutes through the column. UK-Amino, on the other hand, does not show any change in separation or retention. This is a significant development in the history of aminopropyl columns.

UK-Amino's design not only provides analytical power, but the 3um particle high-resolution column has other benefits, including the minimization of LC-MS and LC-ELSD noise levels. UK-Amino can be applied to aqueous normal phase conditions, and separation optimization is possible while comparing to ODS columns using reversed-phase mode. One can expect significant results from this normal phase column of UK-Amino.
