Dedicated Columns
Shim-pack Fast-OA
High-speed analysis of organic acids 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 Analysis of Short-Chain Fatty Acids
Improved Separation: Columns in Series
Peaks 1. Pyruvic acid 2. Succinic acid 3. Formic acid 4. Acetic acid 5. Propionic acid 6. Butyric acid 7. Valeric acid
Peaks 1. Lactic acid 2. Formic acid
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
