How much percentage organics can be analyzed through our ICP-OES 5110 if it is installed with parts compatible with aqueous solution?

It shouldn't be a problem to run high organic acid (like acetic acid) concentration on the 5000 series ICP-OES with a aqueous setup. But a smaller injector diameter should consider to get a more robust setup and to avoid that the plasma shut off due to high vapor load. this should be tested.

And check with different (pump) tubing if they are compatible with the matrix. Viton pump tubing works quite well for acetic acid but more info in the chemical compatibility matrix for the pump tubing. 

Thank you for the prompt response and link to the tubing information. I am working with 30% maleic acid in water. When you say high what is the limit?
