If you cannot find the isotopes of interest in the list below, please contact the laboratory to discuss the possibilities for us to develop the product you need.

In the following list, isotopes in parentheses are present at low abundance or may be subject to interferences. This will result in poorer precision or impaired accuracy unless appropriate measures are taken.

For information about matrices, instumental precision or price, please contact the laboratory.
