A couple of years ago I was occupied with the modeling of chromatography peaks of chemical analysis. Especially the skewedness of peaks. like in the picture shows.

 

Now I came a cross one possible solution to model this behaviour mathematically. Which is pictured in the next rough sketch:

 

Basically this is a sinus on a circular drums edge.

 

And it turns out that the basic formula for this is: 

sin (nD*cos (alpha))

 

 

Now we can clearly see the skewedness of the individual peaks. so this is a valid approach/modeling of skewed chromatography peaks. 

 

 

which looks very similar to this next real chromatography peak that I analyses somewhere a while ago. 

Now there is a nother similar methode to model chromatograph peaks, or just skewed peaks in general:

 

But there is another method to model skewed peaks: which I will mention later.
