Lab Notes

Gas graph.
CO spike once O2 dropped below 8% during the warmup phase.
Spike ends when O2 gets back to 8.8%, at which time it also has higher firebox temperature.
After the spike CO flatlines at around 80 ppm (0.008%).
Slight rise toward the end. Once there is charcoal, the air is shut down at 90 minutes and the test is over
Missing data during flat O2 and stack temp portion of graph, interpolated with an average.
