YMC-Pack Pro

High performance reversed phase columns.

Pro series products begin with a base material in which pore size and pore volume are strictly regulated and the level of metal contamination is carefully minimized.

The processes used for stationary phase synthesis and end-capping are standardized and meticulously controlled, delivering superior batch-to-batch separation reproducibility.

Characteristics

  • Includes C18, C8, and C4 chemistries
  • Very low metal impurities
  • Thorough and complete end-capping
  • Excellent separation of basic compounds
  • Useful for LC/MS
  • Suitable for use in production, R&D, and quality control
  • Excellent durability and reproducibility
