| Inertsil WP300 ( Wide Pore Columns for Protein and Peptide Chromatography ) |
 Super pure wide pore ( 300Å ) silica provides superior chromatography |
 High bonded phase coverage results in sharp and symmetric peaks |
 Rigid silica formulation provides physical and chemical stability |
 Exceptional reproducibility |
 Low operating pressures even in highly aqueous conditions |
| The new Inertsil WP300 series of columns brings the same legendary performance of Inertsil's narrow-pore HPLC products to columns designed for protein and peptide analysis. The WP300 series currently consists of WP300C8, WP300C18, WP300Diol, WP300C4, WP300SIL and Peptide C18. | Inertsil WP300 columns are available in 5 micron particle size in column configurations ranging from capillary to 50mm ID preparative sizes. | |||
