Reversed-Phase Protein/Peptide Columns

Over 50 years of reproducible performance

Semi-preparative Columns with excellent batch-to-batch reproducibility

Polynuclear Aromatic Hydorcarbons (PAHs) are among the most frequently monitored environmental contaminants. Waters PAH columns are optimized for the HPLC analysis of PAHs. These columns achieve baseline resolution and excellent peak symmetry for 16 different target analytes in less than 25 minutes, while employing a simple water/acetonitrile binary gradient method. The resolving power of the PAH columns provides superior pe…

The popular Bondapak® C18 chemistry and Porasil® silica packing material are available in three different particle sizes, 10, 15-20, 37-55 micron, providing easy transfer of chromatography methodology from one particle size to another. You can utilize your existing 10 micron Bondapak or Porasil chromatography as a starting point for scale-up or, if you are developing a new purification protocol, investigate which preparative…

Chemistry choices include: XBridge® Columns, CORTECS® Columns, XSelect Columns, Atlantis® Pola…

MassPREP™ On-Line Desalting Cartridges are an effective tool for the successful desalting of acidic, basic, and large globular proteins. The overall MassPREP™ desalting strategy provides an easy, fast (< 3 minutes), and reproducible approach for the effective desalting of proteins stored in physiological salt buffers prior to high resolution ESI-MS structural analysis.

The polar organic and the polar ionic modes have become increasingly popular largely because of their ideal compatibility with MS detection and preparative LC. Two years of extensive research at Astec in understanding these mechanisms has resulted in new possibilities for extending their effectiveness even further. Important changes in linkage chemistries and the silica and the silica have now led to the new CHIROBIOTIC V2 and…
