    1290 HPLC doesn't operate above 200bar

    data4you

      System 1290

      Pump G4204A

      Openlab A.01.05

      Purchased in 2014. have used 3um particle columns so far. I am trying to use 1.8um particle size columns, but system doesn't operate above 200bar.

      It should work up to 1200 bar based on the spec. No matter how I set up the max pressure limit, actual back pressure is 200bar.

      Is there any way to move the red line to the right in the rectangular bar?
