USP Listing (Quick Guide)
USP classifications vary by method and column chemistry. The guide below lists commonly referenced USP codes used with Benson polymeric columns.
| USP Code | Typical Benson Series | Notes |
|---|---|---|
| L17 | Benson Polymeric Columns | USP L17 refers to polymeric stationary phases based on styrene–divinylbenzene type materials. Benson BP series columns fall under this classification and are widely used for aqueous separations where high chemical stability and long service life are required. |
| L19 | Benson BP-800 Ca Series | USP L19 is commonly associated with polymeric ligand-exchange columns used for carbohydrate analysis. Benson BP-800 Ca columns are designed for sugars and sugar alcohols, providing strong resolution and robustness under elevated-temperature aqueous conditions. |
| L34 | Benson BP H-form Columns | USP L34 typically covers ion-exclusion polymeric packings for organic-acid analysis. Benson H-form columns are widely applied to organic acids, fermentation acids and related analytes in food, beverage and biotechnology samples. |
USP classification alone does not establish an exact equivalent or guarantee identical chromatographic performance. Confirm method suitability under your validated conditions.
