TLDR
In this paper, an air sampling device operated solely by compressed air which is conducted through a venturi tube thereby creating a region of reduced pressure for drawing ambient air into the device where particles or gases carried therein are trapped in a filter type device for analysis.Abstract:
This disclosure relates to an air sampling device operated solely by compressed air which is conducted through a venturi tube thereby creating a region of reduced pressure for drawing ambient air into the device where particles or gases carried therein are trapped in a filter type device for analysis. The device includes a manifold having a plurality of fittings each adapted to receive individual sample-collecting chambers whereby several samples may be taken consecutively.read more
