ABSTRACT:
The present invention is a gravimetric procedure for the measurement of solids and/or liquids in a statically dissipated Teflon bag. The procedure enhances the accuracy of presently accepted laboratory methods because the sample container weighs little relative to the sample and the bag is an inert surface which is not activated or contaminated. Solids placed in the Teflon bag can be treated, weighed, and stored in the bag without any sample transfer. Liquids placed in the Teflon bag are treated and weighed without transfer. This procedure has been applied particularly to laboratory procedures for measurement of particulate samples collected from effluent gas streams during environmental testing.
