For the Savitzky-Golay procedure the solution is in
either reducing the convolution range or choosing a polynomial 
of a higher degree (if the software allows it).

I, personally, prefer manual peak hunting . the most safe and
reliable one. Of course, it takes time (about 5-15 min for  Kalpha2 stripping, 
proper smoothing, calculation of 2-nd derivative curve and mouse clicking) but
it may allow to avoid problems with false or unresolved peaks in the process of 
cell determination.
