Description

Wide pH Stability

• Stability from pH 1 to 13 allows for the analysis of samples at high pH (8-13) without the possibility of column degradation or loss of efficiency. An expanded pH range also allows samples to be chromatographed while ionized.

Good Sample Recovery

• Since PRP-1 is made entirely of poly(styrene-divinylbenzene), there are no silanol groups to cause sample loss, thus the recovery and quantitation of labile and reactive samples is enhanced.

Consistent Reproducibility

• PRP-1 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). Unlike C8 or C18 columns, PRP-1 has no stationary phase coating.

Easy Sample Scale-up

• Columns are available prepacked and tested in a variety of sizes, varying from analytical to semi-prep and preparative scale. Consistent packing material allows linear method scale-up.

Long Life (Excellent Durability)

• PRP-1 columns are packed with a poly(styrene-divinylbenzene) material. This support is pressure stable up to 5,000psi, and cross-linked to prevent shrinkage or swelling (common in other polymeric columns). Since the support is entirely polymeric with no silica to deteriorate, column lifetime is longer for PRP-1 than silica C4, C8 or C18 columns.

• Two column materials: 316 stainless steel and PEEK
• Analytical guard columns
