Hello, I am using PL GPC20 in our lab.Normally when the flow rate is
1.00ml/min,the pump pressure is around 6.4MPa and stable.Now the pump pressure could not increse to 6.4MPa,it is fluctuant between
2.0-3.6MPa.Anyone had same experience with this system?I would greatly appreciate any suggestion.
thank you very much,
