I recently run into some problems with my Waters Alliance e2695 HPLC.
No matter how I set up the system, it will only pump mobile phase in bottle A. I set mobile phase to be 25% A, 25% B, 25% C and 25% D. However, B, C, and D's mobile phase never moved. Only A's mobile phase is going down.
May I ask for some suggestions?
Thanks!
