Hello,

Is there anybody who working about determination of Nickel on metal products. I am using BS EN 1811 method and I get the crm NIST 762 - Nickel reference disk

The disk is 12mm dia and 0,5mm thickness.
Its certificate says that nickel ration on this disc %6,01

My calculation is like that: A(ug/L) * V (10ml) / Area of Disk * 1000 = result (ug/cm2/week)

Area of disk is: 6*6*3,14*0,5 = 0,5652 cm2

After this step i dont know how to calculate? How many should I see on the ICP-MS ?
