Automated system measuring triple oxygen and nitrogen isotope ratios in nitrate using the bacterial method and N

Triple oxygen and nitrogen isotope ratios in nitrate are powerful tools for assessing atmospheric nitrate formation pathways and their contribution to ecosystems. N The main improvements to a previous system are (i) an automated distribution system of nitrate to the bacterial medium, (ii) N The δ An automated system was developed to measure triple oxygen and nitrogen isotopes in nitrate using N
