ABSTRACT:
Diborane is detected in air with high sensitivity (ppb range) and selectivity. The invention is thus suitable for the monitoring of work places and rooms, the emission of plants, etc. The detection is based on an aerosol ionization gas analysis. In addition to an amine, a reagent which does not react with amine is added to the air stream and reacts with the diborane to form a compound which forms aerosols with the amine. The aerosols obtained by this reaction constitute the main measuring effect. When using SO.sub.2 in concentration.gtoreq.3.5 ppm, disturbances due to the SO.sub.2 content of the air are eliminated.
