| Abstract | The recommended operating procedure (ROP) has been prepared for use in research activities conducted by EPA's Air and Energy Engineering Research Laboratory (AEERL). The procedure applies to the measurement of nitrous oxide (N2O) in dry gas samples extracted from gas streams where N2O concentrations range from 0.5 to 200 ppm. N2O concentrations are interpreted by an electron capture detector (ECD). The ECD uses a 63Ni constant current cell. The upper limits of this procedure can be extended by changing the sample loop pressure to reduce the volume of sample in the look or by diluting the sample. ROPs describe non-routine or experimental 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. Use of ROPs must be accompanied by an understanding of their purpose and scope. |
