Howie, thanks for your input. My plan is to use our carbonate digestion
vessel, which has split heads, one is for carbonate and another for H3PO4. I
have some specific questions.
(1) Do you degas waters by means of freeze-thaw-pump cycles before
acidifying? My samples has dominantly bicarbonate. Does this step release CO2?
(2) Do you use a magnetic-bar to help CO2 degas during and after acidification.
(3) Are there any other things to consider?
Thanks for your help.
