Please reposition the bottom of the column holder after Loosen the screw.
- The system flow rate is too high for the current flash column.
- Sample has poor solubility and precipitates from the mobile phase, thus resulting tubing blockage.
- Other reason causes tubing blockage.
The environment is too wet, or the solvent leakage to the inside of the column holder causes short circuit. Please heat the column holder properly by a hair dryer or a hot air gun after power off.
Solvent leakage might be due to the solvent level in the waste bottle is higher than the height of the connector at the base of the column holder.
Place the waste bottle below the operation platform of the instrument, or quickly move down the column holder after removing the column.
This cleaning function is designed to clean the system pipeline before separation run. If “post-cleaning” has been performed after the last separation run, this step could be skipped. If it is not performed, it is recommended to do this cleaning step as instructed by the system prompt.
