Based on the present and projected requirements in stationary source emissions monitoring,the ranking,utility factors and ranges of performance were first established for each of fifteen performance parameters. These desired instrument parameters formed matrix against which the quantified performance values as measured in the laboratory and on an operating power plant flue gas composition could be compared. The comparison of the evaluation data on each performance parameter with the desired performance matrix resulted in an estimate of overall performance of the tested nitrogen oxide monitors. This overall performance is calculated in the form of an 'index of performance'for each instrument. (Author) 收起
