XRF measurement interpretation

[mcspencah]

Hello,

 

I'm doing analysis on potato juice and i just got the XRF analysis results from the lab. The results show many different metal concentrations dissolved in the juice(like potassium and sodium). What do these concentrations mean. Is it the overall metal concentration, including iron complexes for example? Or is it just the ion's in the sample like Fe2+ and Fe3+?

Thanks in advance.

Once again you are short on method statement.

Some presentation of the results wouldn't go amiss either.
