Calibrated in differential mode for check of new secondary standard. Ambient temperature was 23.55C, pressure was 101.98kPa. Using N2 (1600psi) and god bottle 402.69ppm CO2 (1800psi).
Flowing N2 in both sample and reference
CO2 -3.79 - adjusted to 0.0
H2O -0.0863 - adjusted to 0.0
Flowing N2 in reference and god bottel in sample
CO2 = 402.90ppm adjusted to 402.69ppm.
Flowing N2 in reference and new secondary standard in sample, I recorded serial data with Hyperterm and took an average of 201 points. The new tank is 344.62ppm |
