For calculation of Total imp is it right to sum the area of all imp and calculate total imp or is it right to calculate each imp and sum up for Total imp?

Consider response factor 1.0 for all impurities

Bocancea Igor

Did u mean Total imp.=S1+S2+S3+..

or Total imp.=C(%)1+C(%)2+C(%)3+... ?

The first method is the right one: Total imp.=S1+S2+S3+.., then S(total)*100%/S(ref)
