Micro/Capillary: YMC-Pack Polymer C18

Maximum Application Range

YMC-Pack Polymer C18 is prepared from a hydrophilic methacrylate polymer bonded with a hydrophobic octadecylsilane (ODS) reagent.  Because of this, Polymer C18 is compatible with all standard-based ODS reversed-phased solvents, and has a much broader pH range than silica-based ODS.  Compounds such as organic acids, organic amines, peptides, pharmaceuticals, and proteins can be analyzed using Polymer C18.


YMC-Pack Polymer C18: Features & Benefits

Base Material: Polymethacrylate
Stationary Phase: C18 (USP L1)
Particle Size: 6µm
Carbon Load: 10%
Bonding: Monomeric
Endcapping: Not applicable
pH Range: 2-13

Like standard silica-based ODS, Polymer C18 has a hydrophobic bonding (ODS) on a hydrophilic support.  Consequently, its selectivity is more similar to that of silica-based C18 than styrene/DVB-based supports.

  • Utilized hydrophilic polymethacrylate support for performance similar to silica-based ODS
    Methacrylate is functionalized with C18 before polymerization for greater reproducibility
  • No silanols or metal contaminants
  • pH stable from 2-13
  • Compatible with all standard reversed phase solvents
  • No residual silanols or metals

Polymer C18 is a pure organic stationary phase and is not based on a silica gel support.  As such, it has no residual silanols or metal impurities to interfere with the analysis of basic organic compounds.
