The Envirogel high-efficiency GPC cleanup columns are specifically designed to remove low volatility, high molecular weight interferences, such as lipids and natural resins, from environmental samples as specified in EPA Method 3640A. In the past, the cleanup procedure for environmental samples was performed on low-efficiency GPC columns based on packing particle diameters of 37-75 micron (200 to 400 mesh) Bio-Beads S-X resins…

For applications where the sample is neither volume or concentration limited, Waters offers 1 and 2mm Internal Diameter columns of various lengths for use on traditional HPLC MS inlets.As with Waters array of NanoEase™ columns, the same Waters reversed-phase packings are also available in these two column internal diameter offerings. 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.

Waters offers PoraPak™ Rxn, a family of polymer-based chromatography products for superior cleanup of synthetic reactions. PoraPak Rxn products are available in two chemistries: PoraPak Rxn CX, a strong cation-exchange sorbent and PoraPak Rxn RP, a reversed-phase sorbent.PoraPak Rxn sorbents are based on copolymers that exhibit the following properties:Hard material that does not develop increasing back pressure with flowLitt…
