Calibration |
| Notes: |
Calibrated in differential mode for double check of secondary standard. Ambient temperature was 22.52C, pressure was 101.18kPa. Using Zero air (1700psi) and god bottle 421.22ppm CO2 (1700psi).
Flowing zero air in both sample and reference
CO2 -4.15ppm - adjusted to 0.0
H2O 0.0050 - did not adjust
Flowing zero air in reference and god bottle in sample
CO2 = 426.2ppm adjusted to 421.22ppm.
Flowing zero air in reference and secondary standard in sample, I recorded serial data with Hyperterm and took an average of 409 points. The new tank is 337.64ppm |
