Measurement and Results - Internal standards for Zn, Cu, Pb analysis by ICP-MS

 
Recently we installed an ICP-MS for trace elements analysis, and ee would like to know what is the suitable internal standard to be used with our analyzer when analyzing Zinc, Copper & Lead. Your feedback and recommendations are highly appreciated.

Typically, mid-mass range elements utilize scandium (Sc) as an internal standard, so that could be a good choice for zinc (Zn) and copper (Cu). For heavy elements such as lead (Pb), bismuth (Bi) is typically used.  These are monoisotopic elements with very good signal response on ICP-MS.  If scandium or bismuth is in your samples, you may have to choose different elements to use as an internal standard.  If you have any additional questions or concerns, please let us know.
