Calibration |
| Notes: |
This analyzer was calibrated withe the CH4 god bottle then used to measure the CH4 in a 400ppm CO2 secondary tank. In the process the LGR CO2 was calibrated with the scondary CO2 tank.
Last calibration of CH4 and CO2 was on 2011-08-29. The last calibration of H2O was on 2009-03-13.
God bottel: 1.8978ppm CH4 350psi
Secondary CO2: 405.85ppm CO2 -> CH4 determined to be 4.666ppm
CH4 Pre-cal:
8:23PST, 21.67C, 138.20Torr, 13.403usec, 1Hz, 1.9140ppm CH4
After CH4 was 1.8980ppm.
CO2 pre-cal:
8:29PST, 21.65C, 138.18Torr, 13.395usec, 1Hz, 4.666ppm CH4, 413.8ppm CO2
After CO2 was 405.5ppm |
