Dear isogeochemists
Since the dawn of stable isotope geochemistry it has been good
behaviour to spike the phosphoric acid for carbonate reactions with
CrO3. Now my technician tells me that this colourfull compound is
carcenogeneous and she wants (understandably) to avoid it.
Does anybody know why we add it and what would happen if we leave it
out?
Do anybody add it at all or is it just us being old fashioned?
Replies will be appreciated
Bjorn
