Calibration |
| Notes: |
Calibrated in differential mode for double check of secondary standard. Ambient temperature was 24.37C, pressure was 100.54kPa. Using Zero air (400psi) and god bottle 421.22ppm CO2 (400psi).
Flowing zero air in both sample and reference
CO2 0.22ppm - adjusted to 0.06
H2O 0.25 - could not adjust - railed
Flowing zero air in reference and god bottle in sample
CO2 = 420.54ppm adjusted to 421.26ppm.
Flowing zero air in reference and secondary standard in sample, I recorded serial data with Hyperterm and took an average of 100 points. The new tank is 405.83ppm
I accidentally changed the H2O span. I reset to approximately the same value but did not check it with the dew point generator. |
