Real-Time Continuous Monitoring Results (continued)

Andersen Aethalometer

The aethalometer was not available for the 1998 laboratory tests and was available only for part of the field tests. No data are available for the 2000 lab tests because of a configuration problem with a PM2.5 cutoff inlet. The problem was found after testing was complete, voiding the test results.

Field Tests—For the few field tests in which the Andersen aethalometer was used, it overestimated the mass concentration. Figure 36 shows the best-fit line with a slope of 11.99, an intercept of 90 µg/m³, and an R² value of 0.92.

Discussion—Results for the Andersen aethalometer are very limited and should be considered preliminary.

aethalometer compared to the results of a Federal
Reference Method sampler.
