Hello good day, I have a problem with leakage from the purge valve line to the HiP ALS G1367B. When sending flow with 0.25 mL/min the system was pressurized to 240 bar, without connecting column, with the line open. I changed the injector needle, but it did not solve the problem. I changed the needle capillary but it did not solve the problem. I changed the seal of the 6-way valve (rodaine), but it did not solve the problem. I changed the stator but it did not solve the problem either. I only had to change the injector seat, which I replaced, but the problem persists, the liquid starts to leak through the line coming from the purge valve, as if the liquid does not circulate in the 6-way valve. anything else I can do?
Thanks
