BlueShell

by KNAUER

BlueShell UHPLC columns                                         

Vertex Plus column BlueShell C18 A core-shell                         

BueShell columns offer ultra high performance without ultra high pressure: packed with core-shell particles, they provide improved speed, higher resolution, and reduced eluent consumption with moderate HPLC backpressure.

BlueShell features

  • applicable for any type of LC
  • highest separating power (~ 200.000 theoretical plates/meter)
  • multiple columns can be combined for even higher resolution
  • efficiency is comparable with fully porous sub-2 μm particles
  • significantly lower backpressures than sub-2 μm particles
  • high speed and ruggedness

Take advantage of core-shell particle technology

Compared to classical fully porous silica materials, BlueShell particles consist of a solid core and a porous shell. The 2.6 µm diameter particles enable high speed and high resolution separations without undesirable excessive backpressure. The reduced depth of the outer porous layer limits the diffusional path of analytes, leading to minimized mass transfer resistance and minimized peak broadening.

Similar columns from other manufacturers to BlueShell

Up to 10 unique Brand families from other Vendors with the same Mode and the same Modification.

How similarity is calculated
Eligible families receive a weighted score from Modification (25%), Product Usage (20%), Carbon Load (15%), Endcapping (10%), Pore Size (10%), Surface Area (8%), pH Stability (8%) and Particle Size (4%). The score uses data available in both families and requires at least three comparable criteria, at least 50% data coverage and a minimum 55% score. A relevant active sponsor may appear first and is always labelled Sponsored.
A similarity score does not guarantee identical selectivity or performance. Confirm suitability under the intended method conditions.
No other-Vendor Brand family with the same Mode and Modification meets the comparable-data and similarity thresholds.
