Answer / m
Single point threshold is show only peak maxima spectra
whenever peak purity index is shows the front, tail and
peak maxima spectra.
for pure peak we have to consider three point peak purity
which shows that your purity angle should be less than
purity threshold which is clearly shows that your peak is
specrally pure and homogeneous.

Answer / dr. sp goswami
Peak purity index is the purity of peak from its peak apex,
front to tail part considering whole peak examination,
Single point threshold shows only peak maxima spectra .
For pure peak peak purity index should show a positive
value of peak purity index not less than 99 or 1.0 a
negative peak purity index less than 99 shows (shimadzu)
inhomogeneity of peak

Answer / basha
to pass peak purity, peak purity index is greater than
single point threshold

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?
