Updates to instrumentation and protocols for isotopic analysis of nitrate by the denitrifier method.

RATIONALE The denitrifier method allows for highly sensitive measurement of the (15) N/(14) N (δ(15) N value) and (18) O/(16) O (δ(18) O value) of nitrate dissolved in natural waters and for highly sensitive δ(15) N measurement of other N forms (e.g., organic N) that can be converted into nitrate. Here, updates to instrumentation and protocols are described… CONTINUE READING
