Hi,
We are testing 2H enrichment in wild mosquitoes in West Africa as a method to label mosquitoes for life.
So far we have been using desiccated mosquito samples for our analysis, collected alive and kept over silica gel for 2-4 weeks before IRMS (very dry...).
A question arose regarding testing samples that were trapped elsewhere and preserved in 80% EtOH.
Does anyone have an idea if ethanol preservation alters 2H ratios?
Thanks,
Roy
