Technical Note
High sensitivity δ15N analyses
Continuous flow EA-IRMS is a common and widely accepted technique for the determination of the δ15N isotopic ratio. It is also common knowledge that there is an intrinsic difficulty in analyzing samples with a very small nitrogen content due to air inclusion in the sample package.
This Technical Note shows the excellent performance of our EA-IRMS systems for samples with a nitrogen content down to 1 μg.
