High Concentration calculations on Na when the signal intensity for the sample is higher than the blank?

On the sequence tab, did you put a dilution factor in the table? If so, then your values are getting multipled. What instrument do you have?

I understand that the values are getting multiplied - I deal with dilution factors on a daily basis with the chromatography work I do. What I do not understand is why my Na intensities in my samples are falling well below the Na intensity of my blank or lowest concentration standard how to troubleshoot  why this is happening. From what I have been able to diagnose is that the blank Na intensities have gone from close to 0 to 10,000 in the course of a month. I have been systematically going through the system and cleaning and replacing items as needed.

It sounds like sodium contamination from maybe the acids or something in your prep maybe?  Are you storing your solutions in HDPE, Teflon, or borosilicate glass? What acids are you using in your digestion?  Have you checked the cooled cone interface and injector tube to make sure there is no sample residue?
