Calibration |
| Notes: |
I calibrated the LRG with the god bottle and then used it to check two secondary standards. God bottel is 1.8978ppm CH4 and 350psi. Last calibration was 2011-08-23 using 3.276ppm CH4.
Precal: 9:32PST, 23.79C, 156.56Torr, 14.715usec, 1Hz, 1.855ppm
Postcal the CH4 read 1.897ppm.
The older secondary standard with 405.85ppm CO2 read 4.675ppm CH4
The newer secondary standard with 410.49ppm CO2 read 3.228ppm CH4 |
