Under accelerated pH 10.4, 40°C stability test, COSMOCORE C₁₈ column shows superior stability compared with other core shell C₁₈ phases.

COSMOCORE 2.6C₁₈ maintains the same performance as sub-2 µm particles with half the back pressure.

COSMOCORE 2.6C₁₈ delivers performance equivalent to sub-2 µm particles at faster flow rate and analysis time while maintaining a lower back pressure. COSMOCORE can also be used in longer column size to gain additional resolution.

• Retention
  COSMOCORE 2.6C₁₈ features high retention and better separation compared to other core-shell columns

• Higher Loading Capacity
  In general, core-shell particles have less surface area and less bonded phase than fully porous particles. COSMOCORE 2.6C₁₈, however, with a large amount of bonded phase, exhibits both high retention and high loading capacity. When injecting 5-10 times more sample volumes in the trace component analysis, COSMOCORE minimizes peak splitting due to the sample over loading.

COSMOCORE 2.6C₁₈ has low column bleed, and consequently low MS noise level.

COSMOCORE 2.6C₁₈ exhibits high durability. There is no significant deterioration in retention or peak shape after 1,000 injection of amitriptyline.

COSMOCORE 2.6C₁₈ features a special endcapping treatment that effectively shields residual silanol groups, yielding sharp peaks for basic compounds and metal coordination complexes.
