United States Environmental Protection Agency Air and Energy Engineering Research Laboratory Research Triangle Park, NC 27711 Research and Development EPA/600/SR-92/141 December 1992 EPA Project Summary Recommended Operating Procedure No. 56: Collection of Gaseous Grab Samples from Combustion Sources for Nitrous Oxide Measurement Jeffrey V. Ryan and Shawn A. Karns This recommended operating proce- dure (HOP) has been prepared for usŤ in research activities conducted by EPA's Air and Energy Engineering Re- search Laboratory (AEERL). The pro- cedure applies to the collection of gas- eous grab samples from fossil fuel com- bustion sources for subsequent analy- sis of nitrous oxide. This procedure} details only the grab sampling method- ology and associated equipment. This Project Summary was developed by EPA's Air and Energy Engineering Research Laboratory, Research Tri- angle Park, NC, to announce key find- ings of the research project that is fully documented in a separate report of the same title (see Project Report ordering information at back). ROPs describe non-routine or experi- mental research operations where some judgment in application may be warranted. ROPs may not be applicable to activities conducted by other research groups and should not be used in place of standard operating procedures or EPA-approved test methods. Use of ROPs must be ac- companied by an understanding of their purpose and scope. Printed on Recycled Paper ------- Jeffrey V. Ryan and Shawn A.
