Determination heavy metal using ICP-OES

Hello, anyone here know about how to determine heavy metal (Pb,Cd,As,Hg,Sn) in dairy product by using ICP-OES with microwave digestion? i used to determine the sample with axial view, but the linearity just didnt meet, fyi I use seaspray nebulizer and cyclonic spray chamber, and I dilute Sn standar with 0.1 N HCl. Thank you in advance.
