An apparatus for the emission spectrometric determination of nitrogen released into an argon gas stream by chemical reactions in solution.
An apparatus has been constructed primarily for determination of nitrogen released from steels on reaction with organic solvent-halogen mixtures. The nitrogen is collected in a coil and then flushed with argon through a spectroanalyser that is selective to nitrogen and coupled to a recorder and integrator. The integrated signal is linearly related to the mass of nitrogen produced. The apparatus has been tested by determining the yield of nitrogen produced by reaction of hydrazine with a large excess of hypobromite in aqueous solution. For ten 57-microg amounts of hydrazine the average yield of nitrogen was 99%, with a relative standard deviation of 2.4%.
