    1. Create some back pressure after the dectector and suddenly release the pressure. Repeat this several time.
    2. Flow pure organic solvent with how flow rate through your flow cell.
    3. Use syringe to push methanol through the the flow cell.

    You can try the above methods. You can also take out the flow cell to check the presence of bubble.

    也可以冲洗时在废液输出口加点背压。
