How do I adjust an MRM method for 7890/7010 GC/MS/MS.

I have a set MRM method for the 7890/7010 GC/MS/MS.  How do I adjust the acquisition window for one target analyte?  All the other analytes are within the window.  The analyte that I need to adjust is cutting off the shoulder of my peak, about 0.05 seconds.

    maybe.your peak cut off is due.to masshunter quantitative software

    i mean that the GCMS detect the analyte normally but the software uses a narrow time.window

    so you have to go to mass hunter quant--» open your method  --»» edit method----»  retention time setup ( on the left side) 

    and increser your left or right RT Delta
