Designed by a team of Scientists, Marketing Professionals and Customers, Cogent HPLC products use state of the art manufacturing technologies to drive innovation and results together.

Standard HPLC Columns - Cogent HPLC Products start with different particles for separations in HPLC:

  1. Cogent HPS
    Cogent HPS™, Type-B, High Purity Silica with extremely low metal content is available from MicroSolv Technology Corporation or one of our dealers; this product is designed for specific results and is made with a 120A pore size; reproducibility is assured along with characteristics unique to this material. This product is manufactured from highly distilled monofunctional organosilanes for purity and thermally treated with proprietary methods for purity, strength, high surface area and high porosity.

  2. Cogent TYPE-C™ Silica
    TYPE-C Silica™ is based on a Type-B, high purity backbone and is further manufactured to cover the silica with silica-hydride (Si-H) thus replacing 97% of surface silanols (Si-OH). This unique surface along with our proprietary bonding technology results in C18, C8, Amide, Diol, Phenyl, UDA or Cholesterol HPLC columns that have unique character and benefits called Selectivity3™, useful in Reverse Phase, Normal Phase or Aqueous Normal Phase.
