hi,everybody! I am using varian 320 prep,last time I find that the system pressure was too high,about 1600psi at 80ml/min ,but when I disconnect the lines between the column and the detector ,I found that the system pressure did decrease at 990psi,I do believe that somethong wrong with the detector , in fact ,I think that my detector was blocked ,if it is the trueth ,what can I do next?
