| LI-6262 IRG3-1079 | 2013-01-29 | Lab none | Calibration | Lab none | Calibrated in differential mode for check of new secondary standard. Ambient temperature was 22.9C, pressure was 101.84kPa. Using N2 (1600psi) and god bottle 402.69ppm CO2 (1800psi).
Flowing N2 in both sample and reference CO2 -0.53 - adjusted to 0.0 H2O +0.055 - railed but okay Flowing N2 in reference and god bottel in sample CO2 = 401.70ppm 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 300 points. The new tank is 392.30ppm |
