Shim-pack Fast-OA columns are packed with an ion-exclusion polymer, and utilizing an acidic mobile phase, can separate mixture solutions based on the pKa value of each sample component. The Shim-pack Fast-OA is a column for the high speed analysis of organic acids. It can separate multiple organic acids in a short time and supports real-time monitoring of their concentration levels.
Analysis Examples
Conditions
Column : Shim-pack Fast-OA (P/N: 228-59942-41) + Shim-pack Fast-OA (G) (P/N: 228-59942-42)
Mobile Phase : 5 mmol/L p-Toluenesulfonic acid
pH buffering solution : 5 mmol/L p-Toluenesulfonic acid, 20 mmol/L Bis- Tris, 0.1 mmol/L EDTA
Flow Rate : 0.8 mL/min
Detection : Conductivity Detector (CDD-10AVP)
Because the column design is optimized for the high-speed analysis of organic acids, even short-chain fatty acids such as valeric acid are eluted within 10 minutes. If separation with one column is not enough, up to three Shim-pack Fast-OA columns can be connected in series to improve the separation
