I have samples that contain numerous metals. The two metals that I want to run as my majors are Al and Ba. Normally the majors only go up to 2000 ppb. The problem is that I have Ba concentrations in my sample that go up to 3500 ppb. I am short on money and am trying to avoid making a separate dilution for Ba because that will add more time to my run.
Can I just double the amount of Ba standard I add to my major stock to make the Ba calibration go up to 4000 ppb? My main concern here is that at 4000 ppb my calibration would not be linear and that I might overload the detector.
