 The run indicates low moisture content and low sulfur dioxide content, which probably means the sample train had a leak somewhere during the 

sample run.

 Anomalous result. The total particulate catch is much lower than the other two runs. However, the moisture 

content measured during the run with this train is consistent with the other runs.
