Calibration |
| Notes: |
Calibrated in differential mode for check of Frank's new secondary standard. Ambient temperature was 21.349C, pressure was 101.69kPa. Using N2 and god bottle 402.69ppm CO2.
Flowing N2 in both sample and reference
CO2 okay.
H2O okay.
Flowing N2 in reference and god bottel in sample
CO2 = 400.70ppm adjusted to 402.69ppm.
Flowing zero air in reference and new secondary standard in sample, I wrote down about 60 readings and made an average. Frank's secondary standard has 444.44ppm CO2. |
