what is the limit for KF Factor ,we take factor using water we will found factor between 6 to 7 ,while on KF Reagent bottle mentioned 5 mg/ml water content.if we not use dried methanol it is effect on factor.
Answer Posted / ani suryawanshi
Because in KF reagent there is Iodide and the water is neutralize by iodide so the theoretically factor is
MW of Iodide =126.9
H2O =18
126.9÷18 =7.0 so the factor generally gets about 6 to 7

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?
