Abstract
The state of emission spectroscopic 15N-analysis is explained on example of the NOI-6e 15N-anulyzer. This is an analytical instrument with high operation comfort by computer guidance, digital data acquisition and processing by means of a microcomputer. The 15N-abundance can be determined in standard discharge tubes or also in liquid ammonium salt solutions by means of an integrated sample preparation system on 10 μg nitrogen in a short time with a standard-deviation a less than 0.6%.
