Supplier: MICROSOLV TECH CORP
Description: Cogent Amide™ has an amide functional group bonded to the silica-hydride surface direct silicon-carbon bonds. Since the ligand is attached to the surface with direct silicon carbon bonds the bonded phase does not hydrolyze in acidic conditions. Also, it does not make a strong association with acetone.

Supplier: MICROSOLV TECH CORP
Description: Cogent TYPE-C Silica™ is HPLC grade silica with a silica hydride surface. Their unique stationary phase will adsorb and desorb solvents commonly used in mobile phases very differently from ordinary silica resulting in excellent benefits to the chromatographer. Excellent for normal phase chromatography and solvent drying is not needed.

Supplier: MICROSOLV TECH CORP
Description: The many advanced features of the this column produces a very stable, efficient and unique HPLC column with unique selectivity for steroids and other compounds.

Supplier: MICROSOLV TECH CORP
Description: Cogent HPLC columns have a silicon hydride surface similar to other TYPE-C™ phases but the uniqueness of Phenyl Hydride™ is that they have unique selectivity for compounds with aromatic rings with all the TYPE-C silica benefits.

Supplier: MICROSOLV TECH CORP
Description: Using proprietary bonding technology, the straight chain C18 hydrocarbon is bonded directly to the TYPE-C silica-hydride surface at two separate points of attachment with direct siliconcarbon bonds. This Si-C bond is virtually indestructible and confers great stability and longevity to these columns.

Supplier: MICROSOLV TECH CORP
Description: These useful HPLC columns are TYPE-C™ silica columns and have a single, direct silicon-carbon point attachment to the silica-hydride surface.

Supplier: MICROSOLV TECH CORP
Description: Using proprietary bonding technology, the Cogent C8 300™ has a C8 chain bonded directly to the 5 µm, 300A TYPE-C™ silica surface with two separate points of attachment resulting in silcon-carbon bonds.

Supplier: MICROSOLV TECH CORP
Description: These useful HPLC columns have a silica hydride surface similar to other TYPE-C™ phases but the uniqueness of Diamond Hydride™ is that they have a very small amount of carbon on the surface that adjusts the hydrophobicity to a small but important level. This is an excellent choice for small, polar compounds by LCMS or HPLC.
