Reproducibility

Hamilton PRP-h1 reversed phase columns are ideal for applications that require a high degree of column-to-column and batch to batch consistency (i.e., quality assurance, clinical trials). Because of the unique polymer bonding of the C18 to the PS-DVB support, PRP-h1 columns maintain their performance characteristics longer than many C8 or C18 columns. While many column manufacturers rely on other sources for their raw silica support, Hamilton manufactures its PRP-h1 support, thus assuring a consistent supply of PRP-h1 columns.

Long Life (Excellent Durability)

PRP-h1 columns are packed with a poly(styrene-divinylbenzene) material. This support is pressure stable up to 5,000 psi, and highly cross-linked to prevent shrinkage or swelling (common in other polymeric columns). Since the support is polymeric, column lifetime is longer for PRP-h1 than C4, C8 or C18 columns. Regardless of whether you use ion-pair reagents or high percentage aqueous buffers (80-100%) for your separation, PRP-h1 columns outlast silica-based columns under most conditions. PRP-h1 columns will last approximately one year, while C8 and C18 columns will last only 3-4 months.
