I want to use it to analyse dibutyltin in surface water. For tributyltin I have already an internal standard (tributyltin D27) and it is performing very well.
I am trying to buy dibutyltin D18 (about 6 months), but it is not in stock and will be manufactured when there are sufficient orders. This is not the case yet. I did try to use some other internal standards (organotin compounds), but a deuterated dibutyltin compound is the best option. For the analysis I use tetraethylborate for the derivatization reagent.
