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?

If change in specification which parameter require to do for validation? if change in chromtographic condition then which parameter? if api change then which parameter? if change composition then which parameter? if old method not work out then whicj parameter? if additional one impurity added then which parameter of validation require to do on above each conditions? elaborate separately
