#1 System precision (System evaluation)
When you inject single preparation of standard in ten
times/or any number of replicates to the system and the
final result i.e %RSD meets acceptance criteria it shows
that, from injection , elution to detection of your
instrument functioning correctly.
Simply the system precision is evaluation of system.
#2 Method Precision (Method evaluation)
When you inject six preparation of same batch sample in
to your evaluated system,obtained six results should
precise.Then the method used for quantification is correct.
Simply the method precision is one of the testing parameter
to check the method used for the test is reproduble of
results or not.
Don't mitake if the answer is not up to the mark.

I have compare C2H2-air and C2H2-N2O flame AAS on determination calcium. Both use same range of std to plot calibration curve. (2-6ppm) When i measure the sample with phosphate, KCl and LaCl, C2H2-N2O flame give false positive result, around 0.5ppm. When i measure the sample with phosphste, KCl and EDTA. C2H2-N2O flame also give 0.5ppm false positive. But both above mentioned sample would not give false positive when measured by C2H2-air flame. What is the reason?
