Dear Sire Kindly i would like to ask about calibration curve , in the beginning let me say i made 6 strands 1, 2, 5 , 10 , 50& 100 ppb from Cu & Fe the main purpose is to check the Cu & Fe in BHC ( BRINE HEATER CONDENSER), when these strands injected i the ICPOES the calibration coefficient for CU & Fe were 0.999 & 0.981 in respectively , so its accepted like this to complete the test or Fe also must be 0.999. Pls inform me what i have to do in this case
+ahmed massoud Hi. You can use curves with different correlation coefficients (r or r²). You've used different wavelengths and were able to detect 2 different elements, so there will be 2 different r (or r²) values. You don't need have the same value because they're not the same curves, they were made using different parameters only using the same experimental conditions. Bye

is it possible to analyze microelement by this machine
