Detection of gaseous pollutions in the environment and at work places by means of aerosol detectors.
The protection of the free atmosphere and of people at work places requires the development of highly sensitive devices for the assessment of the air-hygiene situation and for the continuous control after measures have been taken. Favourable properties for the solution of such problems are displayed by aerosol detectors, which are suitable for automatic continuous measurements (aerosol ionization gas analyzer AIG) and for applications in gas chromatography (AID-GC). Starting from the principle of measurement the main parameters and properties of both modes of detection for selected pollutions (SO2, NOx, NH3, Ni(CO)4, halocarbons, amines) are given and discussed with consideration of practical experience.
