Chemical Stability and Compatibility - Incompatible metals in solution

We 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, please 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- 
• SO42 - and Pb2+, Ba2+, Cr2O72 -
• 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
