USP L Column Listing



 

 

The following chart has been provided as a guide to selecting SMT HPLC columns which meet the specifications set forth in the United States Pharmacopeia [USP], which provides guidelines for the separation of related compounds.
 
It is important to note that, in many cases, USP column specifications are so broad that several (or many) column types actually meet the basic specications. For example, L1 specification calls for a column consisting of silica packing material, 5 or 10μm in diameter, bonded with octadecyl (C18) silane. However, a limited number of available C18 columns will actually perform the desired separation.
 
SMT offers a variety of columns for each category. These columns are representative of the wide range of selectivities available for each bonded phase. The packing materials vary in particle size, pore size, surface area, carbon load, hydrophobicity, bonded phase coverage or density, and other characteristics. Refer to the catalog for description and characteristics of a specific column of interest.
