  2. Smaller O2 Spikes Correlate with SE Compressor Power Thanks to Rob and Tom for pointing this out!

  3. Larger O2 Spikes Correlate with CM ramps Thanks to Rob and Tom for pointing this out as well!

  4. Latest Transmittane As seen in last weeks slides, O2 spikes seem to have no noticeable effect on transmittance—even when the trans. scan is done at a moment a spike is apparent

  5. What does 6ppm of O2 look like? • The red curve in the plots below corresponds to [O2] = 6ppm, according to the transmittance measurement. • Keep in mind that the O2 ppms as determined by trans. has agreed with the analyzer values to within a ppm or two for just about every trans. plot I’ve produced. • Therefore, it’s safe to say that since we don’t see the same downward shift in the trans. data due to a 6ppm O2 spike, the observed spikes are very likely an ‘electrical’ phenomenon only and do not correspond to actual ppm levels in the gas.
