Key Advantages
Excellent Reproducibility
Manufactured using high-purity silica and tightly controlled bonding processes, Roc columns provide highly reproducible retention times and separation performance from column to column.
Robust Performance for Routine Analysis
The Roc series is specifically designed for routine HPLC applications, making it an ideal choice for quality control laboratories and validated methods requiring long-term consistency.
Broad Application Range
Available in multiple stationary phases, Roc columns support the analysis of acidic, neutral, and moderately basic compounds across a variety of sample matrices.
Excellent Peak Shape
The optimized surface chemistry minimizes unwanted secondary interactions, resulting in improved peak symmetry and reliable quantification for diverse analyte classes.
Selectivity Options
Roc C18 (USP L1)
A highly retentive octadecylsilane (ODS) phase offering strong hydrophobic interactions and excellent peak shape. Ideal as a general-purpose reversed-phase column for a broad range of analytes.
Best for:
- Pharmaceutical compounds
- Environmental contaminants
- Food and beverage testing
- Routine QC methods
Roc C8 (USP L7)
Provides lower hydrophobic retention than C18, enabling faster analyses and improved peak shape for certain basic compounds.
Best for:
- Moderately hydrophobic compounds
- Environmental contaminants
- Fast method development
- High-throughput analyses
Roc Phenyl-Hexyl (USP L11)
Combines hydrophobic interactions with π-π selectivity from the phenyl group, delivering enhanced separation of aromatic and structurally related compounds.
