what is the difference between peak area and peak hight ?
is that can affect the analyzed element concentration if i measure by both ? if yes when i use peak  area and when i use peak hight

Use either as long as you are consistent; there are stochastic models that characterize the difference between using 'area' vs. 'height' but essentially it is just "splitting hairs". If you have well-resolved peaks and a reference standard it don't really matter which you use.

Go Forth with Good luck.

In the 20 odd years I've been doing chromatography, I've generally found that peak area gives a more reliable analysis with much less variability than peak height.

ok gentlmen
but when i work with ICP peaks  the matter is difference
isnt it ?

[Ibin-Huan]

Peak area is more accurate than peak hight because peak area does not effect by broading I mean peak area does not change if parameters are changed.

In our experience, if you modify the run parameters (e.g., change the oven temp, PSIG, etc.) then this causes a change in peak area for the identical sample.  So, that is why I said earlier you may use one or the other as long as you are consistent--though use of peak area is what I prefer and most often cited in the research literature.
