Dear Anita,

I recommend you try using our Interactive Periodic Table. Click on any element of interest and look closely at the Chemical Compatibility data for that element. Additionally I encourage you to see our Sample Preparation Guide which includes highly detailed preparation chemistry for metals and many other elements.

The most common compatibility issues we encounter are as follows:

• Ag⁺ and trace Cl^1-
• SO₄⁼ and Pb²⁺, Ba²⁺, Cr₂O₇⁼
• Rare Earth and Alkaline Earth elements mixed with the "fluoride" elements (Ti, Zr, Nb, Hf, Ta W, Si, Sn, Sb, Ge)
• "Fluoride" elements mixed with higher amounts of any transition elements, especially Sn and W
• Hg at concentrations below 10 ppm or mixed with elements containing organic ligands, such as Antimony Tartrate
• Antimony Tartrate in strong (≥ 5%) nitric acid

I hope this helps. I look forward to hearing from you if you need further assistance.

Serving you in chemistry,
Paul R. Gaines, Ph.D.
