USP classifications vary by method and column chemistry. This page provides commonly referenced USP codes used with Benson polymeric columns. For method suitability, share your USP/EP method details with us.
| 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 lifetime 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 specifically designed for sugars and sugar alcohols, offering excellent resolution and robustness under high‑temperature aqueous conditions. |
| L34 | Benson BP (H‑form) Columns | USP L34 typically covers ion‑exclusion type polymeric packings for organic acid analysis. Benson BP columns in H‑form are widely applied for organic acids, fermentation acids, and related analytes in food, beverage, and biotech applications. |
