how much percentage organic solvent can be added into sample solution if our ICP-MS is installed with parts compatible with aqueous solution? .

Hi 

we came cross a problem with sample solubility. we tried some digestion and are still trying. 

we have some questions about organic solvent for ICP-MS. 

1. our ICP-MS is suitable for aqueous solution.

does it mean we have keep our sample solution 100% aqueous solution? is it able to tolerate a mixture of 50% organic and 50%aqueous solution, or 10% organic and 90% aqueous solution? 

or we have to change our sample cone, skimmer cone, skimmer base and tubings, then we are able to add organic solvent? 

Thank you

best regards,
