Additional Information
Spherisorb OD/Cyano Column, 80Å, 5 µm, 4.6 mm X 250 mm, 1/pk A mixed-mode sorbent made up of Nitrile (CN) and ODS (C18) ligands is used in Spherisorb OD/CN columns. Spherisorb OD/Cyano Columns are general-purpose, propyl cyano bonded columns that offer the best column stability and efficiency, as well as peak symmetry. These long-lasting columns are an excellent complement to laboratory equipment because they provide the most important performance characteristics for any high-quality lab analysis, including column efficiency, peak symmetry, column longevity, and column-to-column repeatability. Spherisorb OD/Cyano Reverse Phase Columns are made in dedicated and tightly managed Waters chromatography chemistry plants, which ensure that the toughest conditions are followed in order to comply with cGMP and ISO 9002 standards. Such stringent conditions at Water facilities help us produce equipment you can trust, and we will give you a column built with only the purest chemicals, as well as many tests to assure you have the best possible equipment.

FAQ
How Is Enrichment Achieved In Low Concentration Sample Components? To enrich sample components that are present at low concentrations, several steps can be followed. You can customize the gradient stages to selectively elute analytes. Using "large" sample volumes in an adsorption-promoting solvent is another useful strategy. Use a "small" collection volume in a desorption-promoting solvent. Use sorbent chemistry that is specific to the analyte and not dependent on the analytical column's chemistry. The chemistry of the solid-phase extraction column should be carefully designed to eliminate the need for any additional sample preparation.
