Cell Pressure=143.19Torr, Cell Temperature=22.14C, Ring Time=11.907usec
2nd CH4 in air at 1400psi
CH4 Span=4.982ppm
CH4 = 4.960 -> 4.982 Offset: 22ppb
Notes: Calibration for check of new 400ppm CO2 cal tank. After calibrating the LGR data was recorded from the new tank. An average of 146 point was 3.875ppm CH4
