Features of RSpak DE Series (5) (Selection of HPLC System)
To realize the best performance of RSpak DE-413 column, we recommend to use the following HPLC system with the column.
| Device | Recommended specifications and/or setting | Example |
|---|---|---|
| Pump | Flow rate: max. 1mL/min. | |
| Injector | Low dead volume type Sample loop: max. 50micro-microL(5micro-L loop is recommended) |
|
| From injector to column |
0.1 to 0.13mmID, 100mm length piping | |
| From column to detector |
0.1mmID piping | |
| Detector | Detector with a micro cell should be used. Response should be set to “FAST”. |
