Steps to Do

Hi, we have a Acquity UPLC/TQD MS system. Unfortunately, it has not been used for a long time. Not being a LCMS guy, I would like to know what things/experiments should done with what samples to make sure everything is O.K.
Also, if someone could direct me to places that I can know more about Acquity LC/MS , that would be much appreciated.

Thanks for your help in advance.
