Depends on your "operation". Your results will be different, you ions you are looking for will change and the responses will alter. If partnered with chromatography it will keep the same RT but generally CI is a softer form of ionisation and EI is harsher.

A full set of CI capable instrument is far more expansive than an EI capability only, So you have a CI installed instrument, congratulations, From Some 5973N and on our CI instrument had given an option to run EI on a CI source, hopefully your instrument is new enough, the idea is even we run daily experiments on CI , still occasionally EI is needed, so Factory design an alternative, after you tuned the PCI tune and passed, you can evoke to generate a EI_CIsource.U tuning file, this means Software will generate a feasible file to run like EI on an CI source, Please, try it!
