Two Met One GT-640s were deployed, one in Missoula and the other in Hamilton. The Missoula instrument had 32 filter comparison test results. The Hamilton instrument had 22 results. Figure 21 shows the results from each instrument. The Met One GT-640 in Missoula (serial No. 5278) had a slope of 0.94x and a y-intercept of -6.15 µg/m3. The correlation coefficient was 0.87. The instrument located in Hamilton (serial No. 1466) underestimated the mass concentration when compared to the gravimetric results. The Met One GT-640 in Hamilton had a slope of 1.67x and a y-intercept of -30.26 µg/m3. The correlation coefficient was 0.99.

federal reference method air samplers deployed at Missoula
(Met One serial No. 5278) and Hamilton, MT (Met One serial No. 1466).
Two DataRams were operated, one in Missoula and the other in Hamilton. A total of 32 results were obtained in Missoula and 27 were obtained in Hamilton (figure 22). DataRam No. 2327, located in Hamilton, overestimated the mass concentration by 2.34 times with a y-intercept of -45.92 µg/m3. The correlation coefficient was 0.98. The other DataRam (serial No. 2484) in Missoula overestimated the mass concentration by 2.61 times with a y-intercept of -32.43 µg/m3. The correlation coefficient was 0.98.
