Waters Acquity UPLC: Is there a way to have an injection occur at a specified time in method?

I would like to inject my sample a few minutes into the method but I could not find a way to do it in the method editor. Is this possible?


  • Hi brclark24,Technically, yes, it is possible.  You could use gradient smart start (in the pump method editor), and choose 'gradient start before injection' and enter the time delay.
    Out of curiosity, why do you want to do this?
