YMC-Pack ODS-A

Fully-endcapped C18 column.

YMC-Pack ODS-A is a high-coverage, fully-endcapped C18 phase which exhibits exceptional lot-to-lot reproducibility. It is available in three different pore sizes and is suitable for the separation of a wide range of compounds.

YMC-Pack ODS-A in 120 Å pore size is the first choice of many chromatographers for high performance reversed phase separations. It has selectivity for the separation of many organic compounds found in pharmaceutical, chemical, and biotechnology industries. 200 Å ODS-A offers a unique mix of moderately large pores and high surface area for the analysis of compounds ranging from small organics and pharmaceuticals to moderately-sized proteins.

Characteristics

  • Highly versatile ODS phase
  • Fully endcapped
  • Selectivity for polar to moderately non-polar pharmaceuticals, organic chemicals, biologicals, and natural products

Applications

Typical applications include: validated API methods
