WebbHi, I am currently using a 1260 ALS autosampler (6 port valve) on my HPLC system. However, every time I inject sample, or simply run my method at "mainpass" mode for the injection port, I can see a significant pressure drop and also leaking from the needle seat. I just changed a new needle seat, needle, rotor seal and isolation seal. Webb25 juli 2015 · The entire HPLC's injection flow path is . continuously washed with mobile phase duri ng the analysis run.
