| Abstract |
An automated system for determining the elemental composition of ambient air has been developed. Airborne particulate matter is collected on up to 36 membrane filters which are sequentially introduced into the sample stream. The duration for the collection period can be adjusted to range from 1 to 24 hours. In the analysis station the elemental composition of the collected particulate matter is determined using an energy dispersive X-ray spectrometer. Each filter is separately analyzed using each of three secondary fluorescers in order to optimize the sensitivity for a wide range of elements which have atomic numbers greater than 12. After a brief analysis period the results for each filter are printed out on a teletypewriter and written on magnetic tape. Up to 36 filters can be accommodated without operator attention.
