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
