| Abstract |
Scott performed a survey of users of the EPA Reference Method for measurement of non-methane hydrocarbons in ambient air which resulted in the compilation of a list of 188 NMHC analyzers operated by 70 organizations. Field evaluations were performed on instruments operated by 16 of the users. The accuracy of the NMHC data being obtained by the 16 users of the reference method was determined by presenting a series of 5 gas mixtures in high-pressure cylinders for analysis by each operator. The results for the mixture containing NMHC at a concentration close to the 0.24 ppm-C ambient air standard showed that substantial errors existed in current NMHC data. An analysis of the data showed that the inaccuracies in current data make it impossible to determine whether ambient air quality is in compliance with the standard. The major factors contributing to data errors are discussed, and recommendations for improving data quality are presented. |
