    I have emailed your request to SQD operator's at Waters. However, as many are on vacation it may be a delayed response.

    Apologies for the delay and I was advised that this should translate easily to SQD. The desolvation gas and temp may need to be increased a bit but should be fine on SQD

    Happy New Year!

    Thanks for the information. It will help in establishing a new method.

    Thank you Liz for your answers, just a little additional information.

    As a starting point for method development, I would suggest using the following parameters for the SQ Detector when using the ACQUITY method from the apps note you originally attached;

    Desolvation Gas Flow; 900L/Hr

    Desolvation Temperature; 400°C

    Source Temperature: 150°C

    These should be good generic starting points for LC methods with flow rates above 0.4mL/min.

    Thanks and all the best,
    Ed
