  • Hello

    Can you tell me what software is controlling the system MassLynx/Empower/ 3rd party and associated instruments and could you also tell us which driver is loaded. Please go to the Console screen and look at "about" menu. Also on the Console System page, what Column Manager firmware is used, just roll the mouse over the image of the Column Manager. If you could include the instrument method settings that would also be helpful. I would like to confirm the temperature band is disabled.

    Many TX

  • Hi Liz,

    The UPLC is running with MassLYnx 4.1.

    The Driver of the console is 1.40.2774 (hope I wrote the good number) and the firmware of the column manager is 1.40.69.

    Please find attached the 2 methods in the attach files:

    Just to let you know that we have 2 pumps (chromatographic pump is used for the gradient, and the regeneration pump) on the UPLC, both is used for method 1 and only one for the second method.

    We have a QTOF premier as well but I didn't put the parameters as it should not have any influence on the UPLC.

    Many thanks
