Hi Juan, it depends on how you prepare your sample, if you are sure it is completely clear you can try to analyse it as it is, maybe diluting it if it is too concentrated. To be on the safe side you usually digest your sample especially, if it is an extract, so you are sure there isn't any residue or solid particles left. Why is it flammable? What solvent is it in? Hope this helps.

Hi Juan

If you have an ICPMS setup for organics analysis, you may give it a try directly, but you will be faced with the fact that calibration standards are probably not easy to find. There are trace metal standards in other organic solvents (often Toluene) but the nebulization efficiency will most likely differ to that of Limonene, which directly affects the sensitivities.

I think your best chance is digestion to measure an aqueous solution that can more easily be calibrated.

Just make sure to either:

- to fully oxidize the organics to avoid matrix effects from organic residues

or

-select an internal standard that reacts in the same way as your analyte to varying organic residues in the ICPMS

Hope this helps,
