Cogent hQ C18

– 3 columns
Vendor: MicroSolv Technology Corporation

The proprietary production of our high purity silica provides us with the control we need to ensure that each batch of silica is made to exacting standards. Our perfectly spherical particles with consistent pore volume and particle size distributions allows our chemists to consistently produce our “new-millennia grade” chromatographic columns and media.

hQ™ specifications include:

  • Silica metal content that is so low, that there is virtually no impact on separation mechanisms as in older brands of silica based columns.
  • Non end-capped “natural silanols” of the silica are part of the separation mechanism without producing peak tailing for many compounds.
  • Particle size distribution that is so tight that no column maker offers greater efficiency.
  • Pore volume that is extremely consistent due to the nature of our proprietary chemical process making resolution extremely reproducible.
  • An incredibly uniform surface area and structure, always perfectly spherical!
