Abstract

On the spectrophotometric determination of traces of Nitrogen Peroxide. — As nitrogen peroxide shows an absorption band coinciding with the sodium D doublet, a sodium vapour lamp has been used as the monochromatic source.

The gas has been examined in layer thicknesses of 1 to 4 m., with 2 barrier layer cells mounted in opposition.

The calibration has been realised by the method of expansion in a known volume.

An appreciable temperature effect, due to the desorption of the gas adsorbed on the tube surface, is noticed.

The limit of detection is nearly one part in a million.
